I think i used calulater and it gives me 47.5
Answer:
Explanation:
The magnetic moment of the coil M = current x area of loop
= I x L x L
M = L² I .
Magnetic field = B
Torque = M x B
= MB sinθ where θ is angle between M and B . Direction of M is perpendicular to face of loop
Torque = MB sin90
= MB
= L² I B .
Answer:
Option (A)
Explanation:
In the process of producing electric energy, always a turbine rotates.
The rotation of turbine is due to the falling water in case of hydroelectric power station, due to the heat energy in thermal power station.
As the turbine rotates, the energy of one form is converted into mechanical energy of turbine. Now the generator converts the mechanical energy into electrical energy. It is done by the electromagnetic induction.
When a magnetic flux linked with a coil changes, the induced emf is developed in the coil, this phenomenon is called electromagnetic induction.
