The source of time varying magnetic field may be
(A) a permanent magnet
(B) an electric field changing linearly with time
(C) direct current
(D) a decelerating charge particle
(E) an antenna fed with a digital signal
Choose the correct answer from the options given below:
Solution
Source of time varying magnetic field may be<br/><br/>
$\rightarrow$ accelerated or retarded charge which produces varying electric and magnetic fields.<br/><br/>
$\rightarrow$ An electric field varying linearly with time will not produce variable magnetic field as current will be constant
