What is the conclusion of magnetism?

Answer: Explanation: The basic law of magnetism states that like poles repel and unlike poles attract. When an electric current is passed through a coil, the coil behaves like a magnet which is called electromagnet.

What is the conclusion of electromagnet?

CONCLUSION. Electromagnets are very easy to build, and they can be controlled. They aren’t dangerous. They are more useful than regular magnets, and they work with electricity.

What is the conclusion of magnetic lines of force?

Magnets attract each other through opposite poles and they repel identical poles. The magnetic field has the direction of the lines of force that leave the north pole of the magnet and enter its south pole. Inside the magnet, the lines of force are parallel and go from south to north.

What is the importance of magnetism?

Maxwell showed mathematically how a changing magnetic field creates a changing electric field (and vice versa). Therefore, magnetism is very important because we use it to create electrical energy. In fact, most of the energy that we use today comes from rotating magnets (see below).

How is a compass affected by other sources of magnetism?

The electromagnet depends on how many times the iron nail was coiled, the more coils the more magnetic force, the less the less magnetic force. From this i can conclude that for a compass to be affected by other sources of magnetism, it must be close to the source, or the magnetic force must be high, then it would affect the compass.

Which is the correct symbol for the magnetic field?

Magnetic field lines reconnect inside a magnet. The symbol for magnetic field is an uppercase, bold B (vector notation) or an uppercase, italic B (for the magnitude only). The reason for this choice of symbol is unknown. The magnetic field is also known as the B field, magnetic flux density, and magnetic induction.

How are permanent magnets different from induced magnets?

Permanent magnets are specially processed ferromagnetic materials that will retain their magnetic state indefinitely. Temporary magnets come in two very different types. Induced magnets are ferromagnetic materials that retain their magnetic state only while in the presence of an external magnetic field.

What are the physical properties of a magnet?

A magnet is an object that exibits magnetic properties such as… exerting an attractive force on iron or other ferromagnetic materials. exerting both attractive and repulsive forces on other magnets. deflecting the path of a moving charged particle. Magnetic Poles Regions on a magnet where the forces are the strongest.
