Electric motors use the electromagnetic force between a magnet and a current carrying coil to produce movement. Electric generators use the electromagnetic force between a magnet and a moving coil to generate electrical energy. Loudspeakers use an electric current flowing through a coil to generate a magnetic field.

What are the practical uses of electromagnetism in your daily lives?
Inventors have harnessed electromagnetic forces to create electric motors, generators, MRI machines, levitating toys, consumer electronics and a host of other invaluable devices that you rely on in everyday life.
What are examples of electromagnetic interactions?
For example, in the hydrogen molecule, the electrons are pushed apart by electromagnetic repulsion towards the extremities, leaving a positive field near the middle. Van der Waal’s interaction holds a hydrogen molecule together. The phenomenon is sometimes called the “hydrogen force”.
Is lightning a static electricity?
Have you ever wondered what causes lightning? Lightning is caused by a buildup of static electricity inside a storm cloud. Moving around inside the cloud are tiny water molecules called hydrometeors. These hydrometeors are colliding and bumping into each other—creating a static electric charge.
What are 10 uses of magnets in our daily life?
Permanent Magnet: uses of magnets in our daily life can be found in the following areas/objects:
- Mobile phones.
- Hard drives.
What applications of electric and magnetic forces do you use in your everyday life?
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.
