What is generated when a permanent magnet is moved in front of a coiled wire and the magnet's magnetic field pushes and pulls electrons in the coiled wire?
an AC, or alternating current
When you make a homemade electromagnet with wire and a nail and a battery does stripping the wire that is coiled around the nail make the electromagnet stronger?
No, this will stop the magnet from functioning and is the same as using a short thick wire instead of a long coiled wire.
What energy is produced when a coiled wire is spun around a magnet?
Electrical
What makes the pickup guitar make sound?
A guitar pickup is wire coiled around a magnet. When the string vibrates, it causes the magnet to vibrate, which creates an electric current in the wire. The signal created by that electric current is then fed into the amplifier which converts it to sound.
What will happen to the electromagnet when current flows in the wire around it?
A coil of wire in which current is flowing is an electromagnet. If to that arrangement you add an iron core, then the magnet will get stronger.
How a dynamo woks?
Dynamo has constant magnet inside.When movement comes up ,magnet starts turning .And outside of magnet has coiled wire .So this movement of magnet causes electromagnetic effect .Finally current consists with this electomagnetic effect.
Why is an electro magnet better than a normal magnet?
An electromagnet is made by wrapping coiled wire around a piece of metal. When a current is applied, it creates a magetic field. The main advantage is that an electromagnet can be turned off by breaking the circuit. That's how those big magnet cranes at junkyards can let go of the metal. You can easily make a fun electromagnet project that kids love. Just coil a wire around a bolt, and hook up the ends to both sides of a battery. A 6 volt flashlight battery works great. More coils means a stronger magnet.
What does the combination of a magnetic field and a coiled wire create strong magnet week magnet or neutral magnet?
it creates a very strong magnet A+ users
How does the strength of the magnet affect the current induced?
The strength of the magnet and its proximity effect the current produced. The magnetic flux density falls quickly so it is important to get close. The stronger the magnet the more lines of flux that pass a point as it moves. Or as something passes by it.
How can the strength of a scrap heap magnet vary?
The strength of a scrap heap magnet vary depending on the strength of the current or number of "turns" in its primary coil. Increasing either or both of these makes the magnet stronger.
What does the combination of a magnetic feild and a coiled wire create?
a very strong magnet.
What can a electromagnet pick up?
Ferrous metals like steel. Electromagnets function the same as any other magnet but are only activated by the introduction of electrical current through an insulated wire that is normally coiled around a core of ferromagnetic material, such as soft iron.
