Question

write a use of magnetic force and frictional force each.​

Answer 1

Answer:

Magnetic force:Computer hard drives use magnetism to store the data on a rotating disk. More complex applications include: televisions, radios, microwave ovens, telephone systems, and computers. An industrial application of magnetic force is an electromagnetic crane that is used for lifting metal objects.   Frictional force:Quite often uses of friction can be seen from how things would be without friction. If there was no friction, you would not be able to walk, drive a car, or hold objects. Pens and pencils would not work. Friction is also necessary to stop a car or bike through the use of brakes.

Answer 2

Answer:

HEY DEAR,

UR ANSWER Is:-

✌️Uses of magnetic force:-

➡️Rotating magnetic fields are used in both electric motors and generators. The interaction of magnetic fields in electric devices such as transformers is conceptualized and investigated as magnetic circuits. Magnetic forces give information about the charge carriers in a material through the Hall effect.⬅️

✌️Uses of frictional force :-

➡️Friction can be a useful force because it prevents our shoes slipping on the pavement when we walk and stops car tyres skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding.⬅️
