Is an electromagnet stronger than a permanent magnet?
Not necessarily. The key difference between a permanent magnet and an electromagnet is the a permanent magnet does not change whereas an electromagnet's magnetic feild can be altered by varying the current through it. This means that electromagnets are more useful because they can be turned on or off, turned up or down or be put in 'reverse'.
What type of wave is the most powerful?
Gamma waves are the most powerful.
Is solar energy powerful?
yes solar energy is somewhat powerful:)
Which type of solar radiation is the most powerful?
gamma rays are the most powerful
The most powerful type of microscope is?
An Atomic Force microscope is the most powerful type
What is an example of a sentence using the word electromagnet?
Electromagnets are widely used now. Instead of traditional magnets.
Can a magnet attract through ceramic tile?
No, but a powerful electromagnet could.
Does using thicker wire make a electromagnet more powerful?
The wire in a electromagnet is the conductive property transferring power. The thicker the wire the more power transferred to the electromagnet for a exponential amount of power.
Is a electromagnet with a six volt lantern battery really powerful or not?
Is a eletromagnet with a six volt lantern battery really powerful or not?
Why might an electromagnet be used to pick up old cars in junk yards?
it is powerful and can be turned on and off easily
How can a electromagnet pick up more metal things?
More than what? - An electromagnet can pick up metal due to its magnetism - assuming it is turned on. If you increase the current, the electromagnet becomes more powerful - but you must be careful not to pass too much current, otherwise the wires might burn through.
What makes an electromagnet powerful?
more coils around the metal object, thicker wire being coiled, and more electricity going to the wire.
What is an electromagn?
If you're talking about an electromagnet, it's a piece of metal, usually iron, that is turned into a powerful magnet when an electric current is run through it. Theoretically, the magnet could be infinitely powerful, if you have an infinite power source.
What is a electromagnet and what does it need to properly function?
A powerful magnet that only creates a magnetic field when a massive amount of power cycles through the magnet. To properly function, the magnet needs to be connected to a powerful source of electricity.
What makes an electromagnet more powerful?
more coils around the metal object, thicker wire being coiled, and more electricity going to the wire.
What is the strongest man made magnet in the world and where is it?
The strongest man-made magnet in the world is the 45 tesla hybrid magnet at the National High Magnetic Field Laboratory in Florida, USA. It combines a resistive magnet with a superconducting magnet to achieve its record-breaking magnetic field strength.
Can you make an electromagnet with aluminum wire?
No. You should use a wire with the best electric conductivity (copper or silver) and wrap it around a (soft) iron core. The wire creates the magnetic field, the iron core concentrates it and turns into a magnet when a voltage is applied to the wire. Iron has rather poor conductivity and malleability so is not suited as the coil of an electromagnet.
