Draw diagram showing the arrangement of the lines of force for a piece of soft iron laid in line with the magnetic field.
Complete the following diagram of magnets to show the lines of force.
The direction of the magnetic lines around a current-carrying conductor can be easily understood using the ______ rule.
A wire 10 cm long carrying a current of 1.5 A is held in a uniform magneÑic field in which B = 10-3 T. Calculate the force on the wire if it is held perpendicular to the lines of the magnetic field.
Assertion (A): Magnetic field lines never intersect each other.
Reason (R): If they intersect, then at the point of intersection, the compass needle would point towards two directions, which is not possible.
