Magnetic field strength refers to the intensity of magnetic field lines in a given area, measured in units of tesla or gauss. Pole strength, on the other hand, refers to the strength of the north or south pole of a magnet, which determines how strong the magnetic field is at that pole. In simpler terms, magnetic field strength is the overall intensity of the magnetic field, while pole strength specifically refers to the strength of individual poles on a magnet.

Why there will be a point between the earth and the moon at which the gravitational field strength will be zero?
At a point between the Earth and the Moon where the gravitational field strength is zero, the gravitational pull from the Earth and the Moon cancels out, resulting in a net force of zero. This point is known as the L1 Lagrange point, where the gravitational forces are balanced due to the interaction between the gravitational pull of the Earth and the Moon.
How is the gravitational field due to the stone related to that due to earth?
The gravitational field due to the stone is much weaker than that due to Earth because of the difference in mass between the two objects. The strength of the gravitational field depends on the mass of the object creating it, so Earth's gravitational field is much stronger due to its significantly larger mass compared to the stone.
How do you reduce the strength of magnetic field?
To reduce the strength of a magnetic field, you can increase the distance between the magnet and the object affected by the field, use a material that can shield or redirect magnetic fields (like mu-metal), or use a magnetic field cancellation system that generates an opposing magnetic field to nullify the original field.
What is the difference between magneticomotive force and magnetic field intensity?
Magnetic field intensity (H) represents how much magnetic field is being generated inside a material, while magneticomotive force (mmf) is the force that drives the magnetic field in a magnetic circuit. In other words, magnetic field intensity is a measure of the magnetic field strength, while magneticomotive force is the magnetic potential responsible for creating the magnetic field.
What does the relative density of lines of a magnetic field tell us about the strength of the field?
The relative density of lines in a magnetic field diagram indicates the strength of the magnetic field in that region. A higher density of lines represents a stronger magnetic field, while a lower density indicates a weaker field. The spacing between the lines also gives an idea of the field's intensity, with closer lines indicating stronger magnetic force.
Can gravity exist without a magnatic field?
It can, and it does. There's no connection between the two.
Does earth have a magnatic field?
Yes
Which planet does not have a magnatic field?
Pluto. Too Cold
What has the most affects the strength of an electric field?
The strength of an electric field is most affected by the magnitude of the charges creating the field and the distance between them. Increasing the magnitudes of the charges or decreasing the distance between them will increase the strength of the electric field.
Is any magnatic field proof material?
Yes, a magnetic field won't penetrate a superconductor. That's called the Meissner effect.
What is the relationship between the charges and field of strength electric?
The relationship between charges and the strength of an electric field is that the strength of the electric field is directly proportional to the magnitude of the charges creating the field. This means that the stronger the charges, the stronger the electric field they produce. Additionally, the distance from the charges also affects the strength of the electric field as it decreases with increasing distance.
How strong is the electric field between two parallel plates 5.2 mm apart if the potential difference between them is 220 V?
The electric field strength between two parallel plates can be calculated using the formula E = V/d, where E is the electric field strength, V is the potential difference, and d is the distance between the plates. Plugging in the values, we get E = 220 V / 5.2 mm = 42.31 kV/m. Thus, the electric field strength between the plates is 42.31 kV/m.
What is the principle of operation of three phase squirrel cage induction motar?
three phase induction motor is like a rotating transformer, works on the principle of faraday's law of electromagnetic induction. when ever three phase supply is given rotating magnetic field is produced (rotating magnetic field is produced because current flowing through each phase is delayed 6.66mSec) and the stationary conductor (rotor) is cut by the rotating magnatic field so emf is induced in the conductor (rotor) since rotor is short circuited current flows and this current produces magnatic field. magnatic field produced by the rotor interacts with the rotating magnatic field. this interaction of fields produces movement in the conductor(rotor)(since it is allowed to rotate).
How electrostatic force balance electron to revolve around nucleus?
because electons make an magnatic field makes the attraction of each electorn to other whether they are of same charge but because of magnatic field they perfom as opposite and attract each other thats why they easly revolve in nucleus
What most affects the strength on an electric field?
The strength of an electric field is most affected by the magnitude of the electric charges creating the field and the distance between the charges. The strength decreases with increasing distance between charges and increases with increasing magnitude of the charges.
Which factor would increase the strength of an electric field between 2 objects?
Decreasing the distance between the objects or increasing the charge of the objects would increase the strength of the electric field between them.
Relationship between flux density and field strength?
In simple terms, if flux density increases, then field strength increases and vice versa. The flux density is equivalent to field strength times with a variable.
