Question

When a charge moves with an uniform velocity, it creates magnetic field along with electric field. But, velocity is itself relative. So, can we say that magnetic field is a relative quantity ? I mean if a charge is moving with a speed of 20 m/s towards east (w.r.t. ground) and I am moving with the same speed of 20 m/s towards east (w.r.t. ground), then in my reference the charge is stationary (it has 0 velocity). So, will it be producing magnetic field ? If the answer is yes, then why ?

​​Most of the answers I got say that, 'the object is actually moving'. But, there is no point in saying that an object is "actually moving". If an object has some velocity, it has to be with respect to some observer or something. Velocity is a relative quantity.​​

Answer 1

Answer:

As there are two types of frame of reference one is inertial frame of reference and other is non inertial frame of reference.

yes charge will produce magnetic field along with electric field with respect to other frame of reference and according to your frame of reference charge will not produce magnetic field.

NOTE: both the frame of reference are correct.

hope it helps u
