People rely on magnets for industrial and commercial use. Since scientists began creating very strong magnets using electricity, magnets have become essential to the medical and electronic sectors. People even rely heavily on magnets in their homes. Briefly discuss three uses of magnets in different fields.

An alloy used to make very strong magnets

Create a concept map using the following words electromagnetism, electrlcity, magnetism, solenoid, electromagnet, magnetic field electromagnetic induction, generators and transformers, motors.

Strong magnetic fields and non-ionising radiations are used in

Strong magnetic fields and non-ionising radiations are used in

Explain the reason for the following in a power generator Strong electromagnets are used as field magnet.

Certain devices can accelerate charged particles to high energies by using combined electric and magnetic fields. Write the names of one such device.

Advanced countries are making use of powerful electromagnets to move trains at very high speed. These trains are called maglev trains (abbreviated from magnetic levitation).These trains float on a guideway and do not run on steel rail tracks. Instead of using a engine based on fossil fuels, they make use of magnetic field forces. The magnetized coils are arranged in the guide way which repels the strong magnets placed in the train's under carriage. This helps train move over the guideway, a technic called electro - dynamic suspension. When current passes in the coils of guideway , a typical magnetic field is set up between the undercarriage of train and guideway which pushes and pull the train along the guideway depending on the requirement. The lack of friction and its aerodynamic style allows the train to more at very high speed. (i) The levitation of the train is due to
