Question

Can magnetic fields exist without electric fields?

Answer 1

Hint: Magnetic field is an area around a magnet within which magnetic force is exerted. It is produced around a permanent magnetic substance or by moving electric charges. Electric fields are generated around particles that have an electric charge. Negative charges are repelled, while positive charges are drawn towards it.

Complete step by step solution:
Electric field is the region around a charge where other charges in that field feel the force of attraction and repulsion. The electric field is represented by electric lines of force. Tangent at any point gives the direction of the electric field.
Magnetic field is a region around the magnet or around a current carrying conductor where magnetic forces are experienced. The presence of the magnetic field is indicated by magnetic field lines. Tangent at any point on magnetic field lines gives the direction of the magnetic field.
A moving charge with constant velocity will always develop both a magnetic field and an electric field, and that’s the reason why both magnetic field and electric field are linked with each other. Magnetic fields and electric fields have nearly the same characteristics. When accelerated charge moves then electric field and magnetic field both are linked and electromagnetic waves are produced and they are correlated with a field called the electromagnetic field. In this electromagnetic field, the electric field and the magnetic field move perpendicular to each other. However, both magnetic fields and electric fields are not dependent on each other. They may also exist independently. Without the electric field, the magnetic field exists in permanent magnets and also with current carrying conductor and without magnetic field, electric field exists in charges at rest. So, both the electric and magnetic fields exist without each other.

So, we conclude that magnetic fields can exist without electric fields and electric fields can also exist without magnetic fields.

Note:
Electric and magnetic fields are both the components related to electromagnetic waves. These two electric components and magnetic components occupy in different planes and these planes are perpendicular to each other and frequency of electromagnetic waves is equal to the frequency of oscillating charge.
