A wire of length 100 m is tightly wounded on a hollow tube of radius 5mm and length 1 m. A current of 1 A is flowing in the wire. Then magnetic field strength inside the tube will be :-

A wire of length 100 m is tightly wounded on a hollow tube of radius 5 mm and length 1m . A current of 1 A is flowing in the wire. Then magnetic field strength inside the tube will be : -

A wire of mass 100 g, length 1 m and current 5 A is balanced in mid air by a magnetic field B, then find the value of B.

A wire of mass 100 g, length 1 m and current 5 A is balanced in mid air by a magnetic field B, then find the value of B.

Two long and parallel wires are at a distance of 0.1m and a current of 5 A is flowing in each of these wires. The force per unit length due to these wires will be
