What happens to the direction of magnetic force when the current is reversed without changing the direction of magnetic field?
Answers
The direction of the current flowing through a wire is what dictates the direction of the magnetic field. This is why they call it Electromagetic. Now if you mean that there was an external magnetic field that the current is travelling through then you would need to state the direction of the field with respect to the current to decide if it is going to affect the current.
When a moving charge is travelling through an external magnetic field, you can use the right hand rule to determine the force vector of the interaction.
It will not deviate any more,
that means it's velocity in terms of magnitude and direction of charged particles remains constant because magnetic field produced by a charged particle is perpendicular to the external magnetic field
hope u get it
