Question

Which is created first an electric field or magnetic field?

Answer 1

Dear student,
Electric fields are created by electric charges. For instance, if you statically charged up a balloon by rubbing it on your hair, the balloon creates an electric field. Magnetic fields are created by magnets. For instance, a fridge magnet creates a magnetic field and uses it to stick to your fridge. Electric fields and magnetic fields are not separate entities.
While electric charges can create electric fields, magnetic fields can also create electric fields. Similarly, while magnets can create magnetic fields, electric fields can also create magnetic fields. In fact, every time you change a magnetic field, you create an electric field. This is called Faraday's Law of Induction. Similarly, every time you change an electric field, you create a magnetic field. This is called the Maxwell-Ampere Law. The interesting thing is that a changing electric field creates a changing magnetic field, which creates a changing electric field, which creates a changing magnetic field, and so on.
