Why does more coils make an electromagnet stronger?
The illustration on the HowStuffWorks website is probably the easiest to understand. As you add coils to the electromagnet you have more and more magnetic field traveling in a certain vector (depending on which way current is flowing). It's much like a lot of physics...as you add horses to a plow the force is increased. As you add coils to an electromagnet the magnetic field increases. As I said, check out this link for better understanding. http://science.howstuffworks.com/electromagnet4.htm\ A wire with an electric current passing through it, generates a magnetic field around it, this is a simple electromagnet. The strength of magnetic field generated is proportional to the amount of current. if we were to increase the number of coils the strength of the magnetic field would increase, also increasing the strength of the magnet
Why does a compass needle change direction when it is near a magnetic field?
Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.
Is magnetic force is contact or non contact?
Magnetic force is a non-contact force.
What is the difference between magnetic force and electric force?
The force is just one aspect of magnetism. For example, there is a magnetic field all around a magnet. Of course they are related, but "magnetism" is a wider term for the entire phenomenon - it may relate to the force, to the magnetic field, or to a few other things.
How is Magnetic flux in a rectangular loop directly related to Magnetic force?
Magnetic flux through a loop is just a measurement of the strength of the magnetic field passing through the loop, and since magnetic field strength is directly related to magnetic force, magnetic force is directly related to the magnetic flux passing through the loop.
What is the controlled variable for an electromagnetic?
One variable that needs to be controlled is the number of coils of the electromagnet as the more coils the stronger the magnetic force, so the same number of coils should be used for each test.
In an electromagnet the magnetic force increase as increase?
Adding more coils will make the magnetic field stronger. Magnetic field increases.
Does color affect magnetic force?
Color does not affect magnetic force. But as magnet gets heated it loses magnetism
How can a change in the voltage of a transformer's primary coil create a change in the secondary coils voltage without the coils touching?
The more coils you have on one side will increase the magnetic force
How can a change in voltage of a transformers primary coil create a change in the secondary coils voltage without the coils touching?
The more coils you have on one side will increase the magnetic force
How does the moon affect the strength of magnetic force?
Not at all
Why do the number of windings around an electromagnet affect the strength of and electromagnet?
This is because an electromagnet gets its magnetic force from the electrons passing through the wire, the more coils there are the more electrons passing through so the more magnetic power. Obviously this only works to an extent since you would need more voltage and so on.
How can a change in the voltage of a transformer's primary coil create a change in the secondary coil's voltage without the coils touching?
The more coils you have on one side will increase the magnetic force

How does radiation affect the atmosphere?
The magnetic force absorbs energy.
Is the region where the magnetic force will affect other magnet?
i guess
How does latitude affect magnetic dip angle?
This phenomenon is due to "dip" or declination of the magnetic lines of force and vary with latitude. Only at the magnetic equator are the lines of force parallel to the surface.
