EVERYDAY SCIENCE

Detailed explanation-1: -Electromagnets are easier to produce. Electromagnets have higher magnetic power than permanent magnets. Reversing the direction of current flow in the solenoid can change the polarity of an electromagnet.

Detailed explanation-2: -Electromagnets have the main benefit of manipulating their magnetic pull strength – both by turning the magnet on or off and by adjusting the current. They also feature greater pull strength than permanent magnets.

Detailed explanation-3: -Advantage of the electromagnets is that they are not permanent magnets and they can be made stronger by giving more amount of electricity. Also, the poles of these magnets can change by changing the direction of the current. By using this property of electromagnets, magnetic separators are made, industrially.

Detailed explanation-4: -Electromagnets can be turned on or off and their strength can be changed by controlling the electric current. An electromagnet is a solenoid wrapped around a bar of iron or other ferromagnetic material. It is stronger if there are more turns in the coil of wire or there is more current flowing through it.

Detailed explanation-5: -Generally, no. The neodymium magnets we provide are also called, “permanent magnets.” The word “permanent” means they stay magnetized for a long time. They are always on. This is the opposite of an electromagnet, where you have to run an electric current through a wire whenever you want it to act like a magnet.
