What is the ultimate fate of an isolated pulsar?
It will slow down, the magnetic field will weaken, and it will become invisible.
How the magnetic field of an electromagnet defends on the current and the number of coils?
The magnetic field of an electromagnet is directly proportional to both the current passing through its coils and the number of coils. Increasing either the current or the number of coils will result in a stronger magnetic field, while decreasing them will weaken the magnetic field. This relationship is described by Ampere's law and the concept of magnetic flux.
Can you summarize Faradays observations on induction?
-- heat (if it isn't a superconductor) -- a magnetic field in the space around the wire
Will the temperature change the magnetic pull of a magnet?
Sure. Heat is tiny movements at the molecular level. A magnetic field want all the atoms to share their electrons in the same direction, therefore stabilizing the heat movements.
What is a region where a magnetic force can be detected?
The magnetic field. If it's an electromagnet, the electromagnetic field.

It will slow down, the magnetic field will weaken, and it will become invisible.
Why can an induction heating process heat magnetic material faster than non magnetic material?
To heat something by induction (which is and oscillating magnetic field), the material has to react to the magnetic field. As the magnetic field is made to oscillate, the molecules of the material are pulled and vibrated in sympathy with the field and their vibration energy increases. Heat IS the vibration of molecules. Thus induction heating will work on a magnetic material but will have no effect on a material that is not magnetically susceptible.
Can a magnetic field go through water?
Yes it can. putting a magnet linked to magnetic object in water will not cause them to separate, only may weaken the attraction
How do you reduce the strength of magnetic field?
you spread them apart.
If an electrical current passes through a conductor what two things are generated?
If an electrical current passes through a conductor, there is an induced voltage (because no conductor has perfectly zero ohms), resulting in power dissipation, and there is a magnetic field, which can interact with other conductors in the vicinity of the first.

If the earth rotated more slowly would you expect it to have as strong a magnetic field?
No it would probably weaken. The Earth's magnetic field is due to a combination of two factors: Earth's relatively high iron content and Earth's relatively high rotation speed. If you reduced either factor you should expect the magnetic field's strength to be reduced.

The area around an object that is affected by the magnetism of that object is the?
A Magnetic Force
Region around a magnet in which magnetic force can act?
Magnetic freild
What is the different electromagnets and permanent magnet?
Electromagnets are non permanent magnets. They got magnetic field because of applied electric field. They lost their magnetic field which was around that, when the applied electric field is stopped. permanent magnets have magnetic property always with it. Permanent magnetic property loses when we heat the material. It cannot be regained once again. But electromagnets are capable of regaining its magnetic properties.
What are temporary magnets?
they have magnetic properties that weaken with time.
