Question

Answer the
(D Study the following principle and answer the questions.
A force is excreted on a current-carrying conductor placed in a magnetic
field. The direction of this force depends on both the direction of the current
and the direction of the magnetic field. This force is maximum when the
direction of the current is perpendicular to the direction of the magnetic
field.
(a) By which law can we determine the direction of the force excreted on the
current-carrying conductor?
(b) In which electrical equipment is this principle used?
(c) Draw a diagram representing the construction of this equipment.
(d) Write the working of this equipment in brief.



I WILL MARK AS BRAINLEST​

Answer 1

Answer:

1 by right thumb law

2 it is used in electric heater

Answer 2

Answer:

(a) Fleming's left hand rule

law is force exerted on current carrying conductor

(b) electric motor devices like fan washing machine etc

(c) refer attachment

(d) as the current flows through the circuit

a force is exerted to armature due to change in magnetic field

thus it rotates
