Why would electromagnet be used in a recycling yard rather than a strong permanent magnet?
Because with an electromagnet, you can turn it off and on - you can pick things up with it then drop them again.
What else can I help you with?
Is an electric bell a permanent magnet?
No, an electric bell typically contains an electromagnet rather than a permanent magnet. When current flows through the coil of wire in the bell, it generates a magnetic field that attracts an iron striker, causing the bell to ring.
When would you want to use an electromagnet rather than a permanent magnet?
You would want to use an electromagnet when you need the magnetic field to be controlled and easily turned on and off, such as in industrial applications like material handling or scrap metal sorting. Electromagnets are versatile as the strength of the magnetic field can be adjusted by changing the electric current flowing through the coil.
Advantage of using electromagnet in an electric motor rather than a permanent magnet?
convert electrical energy to energy of motion...! the usage of an electromagnet allows us to control the flow of electrons to the electric rotor,thereby allowing us to control the working of the rotor,whereas with a permanent magnet there will be a continuous supply of energy which can be stopped only if the magnet is damaged or heated.
What is an advantage of using an electromagnet rather than a regular magnet?
A regular magnet, "Earth Magnet", can be very strong, the disadvantage of using them is that you cannot turn off the magnet. Electromagnet uses the electricity of a common battery and can be turned on and off, such as for switches in a circuit board.
What are the benefits of using an electromagnet rather than a bar manet?
An electro-magnet can be switched on & off - a bar magnet is 'permanent' Think of a scrap-yard. If the magnet they use to pick up huge quantities of metal were permanent, they'd have to manually remove every piece. With an electro-magnet, they simply turn the power on to pick up a load, and off when they want to release it. You can make your own electro-magnet with a battery, some wire and a large nail.
Is an electric bell a permanent magnet?

Why do some electromagnets repel rather than attract?
SOME Electromagnet like permanent magnets have two poles(north/south). Likewise the rules for SOME Electromagnets are the same as those of a permanent magnet(same poles repel, different poles attract).

What is a permanent magnet motor?
A motor with permanent magnets rather than field coilsA:A non-functional contraption often peddled as a free-energy generator.

How are the temporary magnet and the permanent magnet the same?
Both are magnetic.
Would a generator work if the permanent magnet rotate rather than the coil of wire?
I really don't know. :D
Why can't we use a permanent magnet in a scrap yard?
You need to use an electromagnet in a scrap yard so that you can let go of the pieces of scrap that you pick up. A permanent magnet would not allow you to let go.
How do you know that is not a huge permanent magnet earths core?
Scientists have studied the Earth's core extensively using seismic waves and magnetic field measurements. The data show that the Earth's core is primarily made of molten iron and nickel, rather than a solid permanent magnet. Additionally, the Earth's magnetic field is generated by the movement of molten metals in the outer core, not by a single large permanent magnet in the core.
What does electromagnets do?
Electromagnets are temporary magnets that produce a magnetic field when an electric current flows through them. They are commonly used in devices such as electric motors, speakers, and MRI machines. By controlling the flow of electricity, electromagnets can be turned on or off, making them versatile and useful in various applications.
