Question

In a wire , 0.2 metre long current of 2 ampere is flowing wire is kept in a uniform magnetic field making an angle of 45 degree with the direction of field the intensity of the field is 5.0 Newton per ampere metre how much force will be exerted on the wire
​

Answer 1

If the conductor is free to move, it will start moving in the direction of the force. Thus, if a current carrying conductor is placed in a magnetic field, it experiences the Lorentz force (unless the angle between the flow of current and magnetc lines is 0°) !
