Essentially, the magnetic field has to alternate. The alternation causes the flow of electrons (electricity). Electrical, magnetic and mechanical energy are all related. In an electric motor, magenetism and electric current are used to convert to mechanical energy.
If you physically move either the wire or the magnetic field, an electrical energy flow would result. In order to get a large magnitude, you would have to exert a large magnitude of physical mechanical energy or have a very large magnetic energy source.
What else can I help you with?
How do you turn off an electromagnet?
This is what makes a magnet an electromagnet - the ability to turn it on and off... Anyway, electromagnets can be turned off with either the help of a switch, or just by disconnecting the power supply.
Is there a magnet in an electromagnet?
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases. Take a look at this Wikipedia page for more information: http://en.wikipedia.org/wiki/Electromagnet
Why electromagnet is different from a permanent magnet because an electromagnet what?
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
What is a lifting magnet?
A lifting magnet is an electromagnet that is meant to hold or move material that comes in contact with the magnet. This is the opposite of a traction magnet.
What will be attracted or repelled by a magnet?
An aluminum wire carrying current An electromagnet An iron pipe (Apex)
What advantages are there in being to turn a electromagnet on and of?
Being able to turn electromagnetic on and off is what separates it from a normal magnet.
How can you turn off an electromagnet?
An electromagnet requires electric power to be a magnet. You turn it off the same way you turn off a light, by turning the switch.
What is the difference in a common bar magnet and an electromagnet?
The comon bar magnet has two poles, and the electromagnet can be turned on and off also the electromagnet uses electricity to create a magnetic field in the first place. so the difference is normal magnet cant be turned on and off but the electromagnet can. does that answer ur question?
Is an electromagnet likely to be attracted to a magnet?
An electromagnet is simply a device that will create a magnetic field when electricity is run through it (basically a normal magnet, but you need to plug it in). Depending on the magnetic charges of the electromagnet and the regular magnet, it should either attract or repulse like magnets normally do to one another.
What is the difference from a normal magnet to an electromagnet?
A normal magnet is a static magnet that produces a magnetic field without needing an external power source. In contrast, an electromagnet is a magnet created by passing an electric current through a coil of wire, producing a magnetic field that can be turned on and off by controlling the electric current.
How do you turn off an electromagnet?
This is what makes a magnet an electromagnet - the ability to turn it on and off... Anyway, electromagnets can be turned off with either the help of a switch, or just by disconnecting the power supply.
How is an electromagnet different a bar magnet?
a electromagnet is bigger than a bar magnet
Is not a permanent magnet?
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
Which is better a permanent magnet or an electromagnet?
electromagnet
What can you do with an electromagnet that you cannot do with a permanent magnet?
You can control the strength of an electromagnet by adjusting the current flowing through it, which is not possible with a permanent magnet. Additionally, you can turn the electromagnet on and off by controlling the electric current, allowing for greater flexibility in applications such as lifting objects or generating magnetic fields.
What is the function of the switch in the electromagnet crane?
The switch in the electromagnet crane controls the flow of electric current to the electromagnet. It allows the operator to turn the magnet on and off, enabling them to pick up and release loads.
Is a permanent magnet called a hard magnet or a electromagnet?
Perminant magnet
