One major use of magnets is to determine the direction. The other major use is to generate electricity. All generators make use of of permanent or electromagnets to convert Mechanical energy into Electrical energy.
Yes, the "old" televisions use magnetism to controll the movements of the electrons.
No
Penguins use magnetism in order to turn sucrose (a disaccharide) into glucose and fructose (monosaccharides).
No
They don't, they use wings.
no
Yes, it does.
The magnetic hold in coil uses magnetism along with the electric motor that turns the drum.
Penguins
No animal really "detects" magnetism, however animals do use magnetism such as: Pigeon's. little Ions in their brains' line up with the Earth's Magnetic field (EM Field).
Homing pigeons use magnetism through tiny iron crystals in their beaks. Turtles use magnetism by sensing slight differences in magnetism throughout the ocean. It keeps them in the cycle of warm waters in a specific 8,000 mile path that they swim for years.
