Explanation:

63.. because at the point of intersection there will be 2 north poles which is not possible

64... spilt rings change the direction of the flow of current in a electric motor

65... 1.. move the magnet towards or away from coil

2.. increase the current in other coil which should be placed beside the coil

3.. increase the size of magnet

4... increase the length of the coil

66....principle:

it converts electrical energy to mechanical energy

hope it helps you

Explanation:

Explanation:Ans-63.

Explanation:Ans-63.Two magnetic field lines do not intersect each other because if there was point of intersection, The compass needle would point towards 2 directions. Which means that the magnetic field has two different directions, which is not possible.

Explanation:Ans-63.Two magnetic field lines do not intersect each other because if there was point of intersection, The compass needle would point towards 2 directions. Which means that the magnetic field has two different directions, which is not possible.Ans-64.Split ring is used for reversing the direction of current in the coil. ... Therefore, after every half rotation of the coil the direction of the couple rotating the coil remains the same and the coil continues its rotation in the same direction.

Therefore, after every half rotation of the coil the direction of the couple rotating the coil remains the same and the coil continues its rotation in the same direction.Ans-65.The different ways to induce current in a coil are as follows: (i) If a coil is moved rapidly between the two poles of a horse-shoe magnet, then an electric current is induced in the coil. (ii) If a magnet is moved relative to a coil, then an electric current is induced in the coil.

A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
