Does a magnetic field exist around every object?
Yes, a magnetic field exists around every object that has a magnetic property.
Why is there a magnetic field even when there is no current?
A magnetic field can exist without current due to the intrinsic magnetic properties of particles like electrons. In atoms and materials, the alignment of these particles' spins can create a magnetic field. This is known as magnetism and is responsible for phenomena like the Earth's magnetic field.
When and magnetic fields both exist it is called an electromagnetic field.?
Yes, an electromagnetic field refers to the combination of electric and magnetic fields that are generated by electric charges and changing magnetic fields. This field propagates through space and carries electromagnetic energy.
When what and magnetic fields both exist it is called an electromanetic field?
An electromagnetic field is a physical field produced by electrically charged particles. It consists of electric fields and magnetic fields that interact with each other. When both electric and magnetic fields coexist, they form an electromagnetic field.
What is the divergence of magnetic field intensity?
The divergence of magnetic field intensity is zero. This is because magnetic monopoles do not exist, meaning that the field lines always form closed loops and do not have sources or sinks. Mathematically, this is represented by Gauss's law for magnetism, ∇⋅B = 0.
