Question

the phenomenon by which a magnetic substances becomes a magnet when it is place near a magnet​

Answer 1

Answer:

the phenomenon by which a magnetic substance becomes a magnet when it is place near a magnet is called Paramagnetism..

Answer 2

Answer:

Concept:

    Magnetic induction is the creation of an electromotive force across an electrical conductor in a fluctuating magnetic field. The process of magnetic induction makes magnetic materials like steel and iron into magnets.

Explanation:

• F=q(E + v B) B in this case stands for the magnetic field or magnetic induction. The magnetic flux density, often known as the number of flux lines crossing per unit area, is another way to define B.
• Tesla is the SI unit for magnetic induction (B). One weber per square meter is equivalent to one tesla.
• The gauss, commonly known as the "magnetic flux density" or the "magnetic induction," is the cgs unit of measurement for a magnetic field B.

• There are many various kinds of materials that can be used to make magnets, including iron, nickel, nickel alloys, chromium, and cobalt. Some of these minerals, like nickel and cobalt, exhibit very low magnetic amounts on their own in their native states.

Electromagnetic Induction Applications

    We now have Faraday's law, which is based on his experiments and states that the voltage induced in a coil is proportional to the number of turns and the rate of changing magnetic field.

• The electromagnetic induction theory underlies the operation of AC generators.
• Electromagnetic induction underlies the operation of electrical transformers.
• On electromagnetic induction, the magnetic flow meter is built.

Hence the phenomenon by which a magnetic substances becomes a magnet when it is place near a magnet​ is called magnetic induction.
