Answer:
Hello mate
Explanation:
Repulsion is the surest test of magnetism because the attraction can be caused between two unlike poles of the two magnets or between the magnet and magnetic substance such as iron, nickel etc. But repulsion is caused when two similar poles approach each other
Answer:
Electromagnetic Induction is the process of using magnetic fields to produce voltage, and in a closed circuit, a current. So how much voltage (emf) can be induced into the coil using just magnetism.
The rule is : Whenever the number of magnetic lines of force are passing through a coil changes , a current is induced in the coil. This rule is known as Faraday's law of induction. The process by which a changing magnetic field in a conductor induces a current in another conductor is called electromagnetic induction.
