A current is passed through a straight wire bent at a point. The magnetic field established around it has its lines offorces :

"On passing current in a conducting wire, the magnetic field is produced around it." It is a law of

"On passing current in a conducting wire, the magnetic field is produced around it." It is a law of

An electric current passes through a straight wire. At a distance 5 cm from the wire the magnetic field is B. The field at 20 cm from the wire would be

When electric current passes through a wire, "_______" field is created around it.

When electric current I flow through a straight wire of length I placed in a magnetic field , a magnetic force of 1N acts on it . If magneitude of the electric current is halved and the magnetic field is doubled , what will be the magnetic force acting on the wire ?

An electric current passes through a long straight wire. At a distance 5 cm from the wire the magnetic field is B . The field at 20 cm from the wire would be

An electric current passes through a long straight wire. At a distance 5 cm from the wire, the magnetic field is B. The field at 20 cm from the wire would be
