What types of magnets are harder to magnetize but retain magnetism much longer?
permanent magnets
What is true of permanent magnets?
Permanent magnets contain a current-carrying wire.
Are permanent magnets only attracted to other permanent magnets?
No, they are attracted to: Other permanent magnets Solenoids Iron Wires with current running through them
What force of two similar ends of magnets produce?
Magnets always produce an electromagnetic force- between the similar ends of magnets it is electromagnetic repulsion.
What is PMDC motors?
PMDC-Permanent Magnet DC motor is a DC machine where the Permanent Magnets form the stator of the machine instead of conventional Field winding. It works on the same principle of electromagnetic induction.
How are permanent magnets bad?
Permanent magnets aren't bad. period. I do not know where you heard that but whatevs..
Where can I find permanent magnets?
Permanent magnets can be purchased from sites such as Magnet Sales and PML India. A permanent magnet is more resistant to factors that would demagnetise it than regular magnets.
What is the difference between a permanent and non permanent magnet?
Permanent magnets are bar magnets or horse shoe magnets which has magnetism at all times. But non permanent also known as temporary magnets are usually electromagnets which would have magnetism only when current flows through the coil that surrounds it.
What type of magnets are harder to magnets but retains magnetism much longer?
permanent magnets
A permanent magnet can affect?
A permanent magnet can affect magnets and electromagnets.
Why aren't permanent magnets really permanent?
They can be demagnetized. Because nothing can be permanent :-)
How are temporary and permanent magnets alike?
Yes Permanent magnets is the term used to describe magnets that are always magnetic, an non permanent magnet would be an electro magnet which is only a magnet when an electric current is put through it.
