Magnetic and electrical fields are related, and magnetism, along with gravity and strong and weak atomic forces, is one of the four fundamental forces in the universe. But none of those facts answers the most basic question: What exactly makes a magnet stick to certain metals? Or why don't...
4. To use outdoors, fasten paper to a pencil with thread. Place the pencil on the top of a glass jar with the needle hanging inside the cup. Now watch as the needle spins and points north. 5. Turn the jar in place. Does the needle continue to point north?The metallic core of the...
Essentially a compass is a light weight magnet, generally a magnetized needle, on a free rotating pivot. This allows the needle to better react to nearby magnetic fields. Since opposites attract the southern pole of the needle is attracted to the Earth’s natural magnetic north pole. This is ...
This would only happen if there were a magnetic field present to interfere with the needle of the compass, so he deduced that a magnetic field produced electricity from the battery. But Oersted gravitated toward the field of chemistry and left the research of electricity and magnetism to others...

A compass works because its magnetic needle is attracted by the magnetism of Earth, which draws it to point to the constantly shifting Magnetic North pole. The Geographic North pole, on the other hand, is static and is located 1,200 miles (1,931 kilometers) north of the Magnetic pole. ...
This current generates a magnetic charge, and this natural magnetism of the Earth is what makes a compass work. A compass always points north because the metal needle is attracted to the pull of the North Pole. Electromagnets All Around Us Many electromagnets have an advantage over permanent ...

What advantage is there in using a set of Helmholtz coils over just a single small magnet? What device could use the earth's magnetic felds to produce energy, and how would it work? Why does increasing the temperature of a magnet decrease its magnetism? Why do indu...
