The force on an electron moving in a magnetic field will be the largest when its direction is?
perpendicular to the magnetic field direction
How do you reverse the direction of a magnetic field?
You can reverse the direction of a magnetic field by changing the direction of the electric current flowing through a conductor. This is known as the right-hand rule - if you pass your right-hand thumb in the direction of the current flow, your fingers will curl in the direction of the magnetic field. By reversing the direction of the current, you can reverse the direction of the magnetic field.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The magnetic field direction around the wire reverses when the direction of the current in the wire is changed. This is due to the right-hand rule that states the direction of the magnetic field is perpendicular to the direction of current flow.
What device can be used to determine the direction of the magnetic field in the electromagnet?
A compass can be used to determine the direction of the magnetic field in an electromagnet. The needle of the compass will align along the direction of the magnetic field lines produced by the electromagnet.
How do you change the direction of a magnetic field?
You can change the direction of a magnetic field by reversing the flow of electric current in a wire or by changing the orientation of a permanent magnet. Alternating the direction of current in a coil can also reverse the direction of the magnetic field it produces.

How can the direction of magnetic field lines at a place can be determined?
Get a magnet that's free to turn in any direction ... a boy-scout compass will do nicely.Place it in the magnetic field. It rotates to point in the direction of the field 'lines' atthat location. (I forget whether it's the north or south pole of the compass that pointsin the direction of the magnetic field, or opposite to it.)If you like, move your detector slowly, always following the direction in which it points,and you'll trace out a complete 'line' of the magnetic field.

How can you reverse the direction of the magnetic field in a wire produced by an electric current?
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.

Which happens to the magnetic field of a wire when you change the direction of the current in the wire The magnetic field?
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
What device can be used to determine the direction of the magnetic field in the electromagnet?
A compass can be used to determine the direction of the magnetic field in an electromagnet. The needle of the compass will align along the direction of the magnetic field lines produced by the electromagnet.

What do magnetic field line show?
Magnetic field lines show the direction in which a magnetic north pole would be attracted. They provide a visual representation of the strength and direction of the magnetic field in a given space.
What is the magnetic field around a wire when the current running in the wire is in reverse direction?
The magnetic field around a wire is determined by the direction of the current flow. If the current running in the wire is in the reverse direction, the magnetic field around the wire will also be reversed. The direction of the magnetic field is determined by the right-hand rule, where if you wrap your right hand around the wire with your thumb pointing in the direction of the current, your fingers will point in the direction of the magnetic field.
Why Do transverse magnetic mode has no magnetic line is in direction of propagation?
No. It has. Since transverse electric mode has it's wave propagating in the Z direction, and has magnetic field existing in the same direction with NO electric field... Likewise, transverse magnetic mode has it's wave propagating in the Z direction and has electric field existing in the same direction with NO magnetic field.
What happens to a current carrying wire in a magnetic field when it is reversed?
When the direction of the current in a wire is reversed in a magnetic field, the direction of the force acting on the wire also reverses. This causes the wire to move in the opposite direction within the magnetic field.
