Electro Magnetic Induction

scientist behind of Electro Magnetism

• Ampere

• Oersted

• Faraday

• Henry

SI unit of Magnetic flux is

• Waber

• Weber

• Watt

• Tesla

Magnetic flux depends upon

• Area

• Magnetic field

• Angle between Area vector and Magnetic field

• All of the above

"The polarity of induced emf is such that it tends to produce a current which opposes the change in magnetic flux what produced it" given by

• Faraday law

• Ampere circuital law

• Biot savart law

• Lenz's law

Electro magnetic induction played an important role in technological development
