What condition is necessary for an electric charge to have a magnetic field around it?
|
It must be in a copper wire. |
||
|
It must be isolated from the opposite charge. |
||
|
It must be moving. |
||
|
It must be motionless. |
IT must be moving
if there is electric charge there must be some electric field around it and also by using formula F=qv X B
for magnetic force around that charge that charge must have some non zero velocity.
