(a) Magnetic induction occurs when a conductor placed in a magnetic field changes direction or moves across the line of flux of the magnetic field.
(b) A magnet can attract unmagnetized material when the field from the magnet aligns the magnetic dipoles of the unmagnetized material.
What is magnetic induction?
Magnetic induction or Electromagnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field.
How unmagnetized material is attracted to a magnet
A magnet can attract unmagnetized material when the field from the magnet aligns the magnetic dipoles of the unmagnetized material so that they match those of the magnet itself.
