Summary of the given simulation
Only motion of magnet induce emf
Only Motion of coil induce emf
Relative motion between coil and magnet induce emf
without any movement between them we can get induce emf
Magnetic flux depends on
Magnetic Field
Area
Angle between Magnetic Field and Area Vector
All of the above
The magnitude of the induced emf in a circuit is equal to the magnetic flux through the circuit
True
False
identify the Law depicted in the given diagram
(a)
Give the formula of motional emf
(a)
changing magnetic fields can set up current loops in nearby metal bodies. they dissipate electrical energy as heat, such currents are called
Henry Currents
Faraday Currents
Eddy currents
Inductance current
Write the parameters on which self inductance of the coil depends
in a closed circuit, electric currents are induced so as to oppose the changing magnetic flux as per
Law of conservation of mass
Law of conservation of charge
Law of conservation of energy
Law of conservation of current
write the application of eddy currents...
