Write one use of magnetic force and frictional force
Answers
Explanation:
An industrial application of magnetic force is an electromagnetic crane that is used for lifting metal objects. For example: friction between our shoes and the floor stop us from slipping. ... friction between the brakes and wheel help bikes and cars to slow down
Answer and Explanation:
Magnets have north poles and south poles: opposite poles attract, and like poles repel. We can use this to our advantage. We can use magnetism to apply force to objects: to attract and repel them.
Examples of magnetic force is a compass, a motor, the magnets that hold stuff on the refrigerator, train tracks, and new roller coasters. ... All moving charges give rise to a magnetic field and the charges that move through its regions, experience a force.
Friction is a resistance force that slows down or prevents motion, it is necessary for many applications where you might want to hold items or do things and prevent slipping or sliding. Friction is used in car brakes, when we walk or climb a hill, making a fire, skiing down a hill, and more.
When the head of the matchstick is rubbed against a rough surface, heat is generated and this heat converts red phosphorous to white phosphorous. White phosphorous is highly inflammable and the match stick ignites. Sometimes, matchsticks fail to ignite due to the presence of water. Water lowers friction.
