Does Magnetic forces act when electrons move?

Yes. To be more accurate, a magnetic field is caused whenever there are moving electrical charges. Even the magnetic field in a permanent magnet are caused by more electrons moving around their atoms in one direction, than in the other.Yes.

Does electricity flow through wire or around its magnetic field?

Eiectricity flows through wire not around the magnetic field.


A current in a long straight wire produces a magnetic field. These magnetic field lines?

The magnetic field lines are arranged circularly around the wire.

What is pushing or pulling force that exists when a magnetic material is near?

Magnetic field


Why there exists magnetic Field when there is no magnetic charges practically?

A magnetic field is induced by moving electric charges, either by an actual electric current, or the way that electrons (charged particles) spin around the nucleus [in the case of magnetic materials becoming magnetized].


What is the simple definition or what is biotsavarts law?

An electric current produces a magnetic field around wires where the current exists.


What is the relationship between magnetic fields and electricity?

-- A current flowing through a conductor creates a magnetic field around the conductor. -- Moving a conductor through a constant magnetic field creates a current in the conductor. -- If there's a conductor sitting motionless in a magnetic field, a current flows in the conductor whenever the strength or direction of the magnetic field changes.


Where is the field around a magnet strongest?

Where is the magnetic field around a magnet strongest? Answer: A magnetic field is strongest around the poles. Your welcome! :)
