Question

1) construction of which payment does the above
diagram shows in question ?
2) on which principle does the equipment work ?
3) according to which law does the coil ABCD rotate ?
4) write the law in your word ?
5) where is equipment used ?​

Answer 1

Answer:

This is construction of electric Motor.

When current carrying coil is placed in strong magnetic field then it will experience torque on it.

So here it converts electrical energy into mechanical energy

$\tau = M \times B$

Explanation:

1) Above diagram shows the construction of electric motor

2) It works on the principle that when a current carrying coil is placed in uniform magnetic field then it will experience torque.

So we can say

$\tau = \vec M \times \vec B$

where we know

M = magnetic moment of coil

B = magnetic field due to magnets

3) As per the law of Faraday the magnetic flux linked with the coil is interacted with the magnetic field of the magnet

so here it will rotate the coil between the two magnets

4) the torque due to which the coil will rotate is given as

$\tau = M \times B$

here we know

M = N i A

N = number of turns

i = current in the coil

A = Area of the coil

5) Equipment is used in many mechanical operation where we need mechanical energy

So here it converts electrical energy into mechanical energy
