An electromagnet is a type of magnet whose magnetic properties stem from electricity. The earth has a lot of electromagnet waves running through it's surface, which come from the polarization of the planet. A more simple electromagnet can be made by wrapping wire around a metal object and connecting the wire to a battery (just be careful).
What else can I help you with?
What is the source of energy is the electromagnet?
oil
How do you make a remote to electromagnet?
To make a remote-controlled electromagnet, you would need a remote control system, an electromagnet, and a power source. You can connect the power source to the electromagnet through a relay controlled by the remote system, allowing you to turn the electromagnet on and off wirelessly. This setup would enable you to control the magnetic force remotely.
Can a electromagnet act as a magnet when the source is dc?
yes it can
What changes will result in a weaker electromagnet?
Increasing the resistance in the wire, reducing the number of coils in the electromagnet, and using a weaker power source will all result in a weaker electromagnet.
What happens when you remove the power source from an electromagnet?
When you remove the power source from an electromagnet, the magnetic field that was being generated by the flow of electric current through the coils of the electromagnet dissipates. As a result, the electromagnet loses its magnetic properties and no longer attracts or repels magnetic materials.
How do you create electromagnetic energy?
a ___________________ is he energy source when creating an electromagnet
Do you have to connect a cell to work an electromagnet?
A cell or other (DC) power source must, indeed, be connected to an electromagnet to make it work. It is an electromagnet. Surf the link to our friends at Wikipedia. It's a good article, and the pics are cool.
Can the strength of an electromagnet be changed by changing the voltage of the Power Source?
Yes, the strength of an electromagnet can be changed by changing the voltage of the power source. Increasing the voltage increases the current flowing through the electromagnet, which in turn increases its magnetic field strength. Conversely, decreasing the voltage decreases the magnetic field strength.
Ivan wants to build an electromagnet. What three materials will Ivan need?
Ivan will need a power source (such as a battery), a coil of wire, and an iron core to build an electromagnet.
What is the source of electricity in the electromagnets?
The source for an electromagnet can be any electrical supply. Batteries or derived from the mains, using a transformed and rectified supply.
What do you need to make and electromagnet?
To make an electromagnet, you will need a core material (such as iron or steel), insulated copper wire, a power source (such as a battery or power supply), and a way to connect the wire to the power source (such as a switch). Simply wrap the wire around the core material, connect the ends of the wire to the power source, and when current flows through the wire, it will create a magnetic field in the core, turning it into an electromagnet.
How the poles of an electromagnet can be reversed?
The poles of an electromagnet can be reversed by changing the direction of the current flowing through the coil of wire. By switching the positive and negative terminals of the power source, the magnetic field produced by the electromagnet will also reverse, causing the poles to switch.
