Turning a magnet very quickly would be best used to create a) radiation. reactivate b) light waves. reactivate c) an electric current. d) a convection current.

Turning a magnet very quickly would be BEST used to create an electric current

In Electromagnetic waves electric field produces magnetic field and vice versa. A moving magnet can produce electric current. Dynamo is the best example for it. In dynamo armature is rotated between the magnets which results in the development of electric field and hence an electric current is produced in it.

C) an electric current

Explanation:

Changing magnetic field induces electromotive force which results in electric current to flow in conducting wire.

From Faraday's Law:

induced emf,

Thus, when magnet is quickly turned, a change in magnetic field would produce an electric current.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
