the understanding electromagnet
Electromagnets are the process of changing magnetic objects because of the flow of electricity. Electromagnets can be met on loudspeakers, transformers, electric bell and so on. How does electromagnet work?
Electromagnet occurs in the electricity flowing through the wire so the wire will appear Magnetic field
The greater the electric current that flows the resulting magnetic field will be stronger. The magnetic field can also be reinforced by wire wrapping to form a coil
More about more about electromagnetic understanding is as follows
how does electromagnet work
When an electric current flows through the coil than on the coil will form a magnetic field, the greater the electric current the stronger the magnetic field generated
When the magnet appears and the coil is held close to a piece of iron the pieces of iron will be attracted. This event is called an electromagnet
magnetism can also be strengthened by inserting an iron core into the coil. Electromagnet is temporary means the electric current is disconnected from the source then the magnetic field will be lost
things that affect electromagnetic weakness
Strong weak Magnetic field is influenced by several things
– large electric current
The greater the electric current flowing into the coil the stronger the magnetic field is generated and vice versa if the electric current flowing is small then the resulting magnetic field will be weak
-the amount of coil
The more the number of wire reels the stronger the magnetic field is generated and the vice versa if the number of coil is small then the resulting magnetic field will become weak
the smaller the resistance of the wire used to make the coil The magnetic field will be stronger, the more resistant the wire is used The magnetic field will weaken
by inserting the core iron into the coil then the resulting magnetic field will be stronger than the coil without the iron core
electromagnet will occur when the current of both DC and AC current flow into the coil
One example of the benefits of an electromagnet is a transformer or transformer
- what is LDR and how does it work?
- what is ring counter and how does it work?
- power supply without transformer
If an electric current flowing is an AC current it will produce an electromagnetic wave
