Some of the questions and their solutions from NCERT Solutions for Class 10: Magnetic Effects of Electric Current, are as follows:

Q. Why does a compass needle get deflected when brought near a bar magnet?

Sol. Compass needle get deflected when brought near a bar magnet as its magnetic field lines interact with that of the bar magnet.

Q. Why don’t two magnetic lines of force intersect each other?

Sol. Magnetic lines are parallel to each other. Thus, they can’t intersect. Also, if two field lines of a magnet intersect, then at the point of intersection, the compass needle points in two different directions. Thus, two field lines do not intersect each other.

Q. Choose the correct option.

The magnetic field inside a long straight solenoid-carrying current

(a) Is zero

(b) decreases as we move towards its end

(c) increases as we move towards its end

(d) Is the same at all points?

Sol. (d)The magnetic field inside a long, straight, current-carrying solenoid is uniform. It is the same at all points inside the solenoid.

Q. What is the role of the split ring in an electric motor?

Sol.  The split ring in the electric motor acts as a commutator. The commutator reverses the direction of current flowing through the coil after each half rotation of the coil. This reversal action of current helps in continuous rotation in the same direction.
