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
What happens to the strength of an electromagnet when the voltage in the coils of the solenoid is decreased?
The greater the current in the coil, the stronger the magnetic field will grow. Conversely, lowering the battery voltage decreases the current, weakening the field.
Does the number of coil of wire in an electromagnet affect its magnetic strength?
yes,the more the coils the more the strength it collects
What happens to Dielectric strength when heated?
it decreases in strength in meany ways for different materials for exsample, with gases if there is an increase in humidity, then it decreases the dielectric strength
What factors of an electromagnet affect the strength of the magnetic field?
One of them is how many coils go around the electromagnet. also the amout of current flow< and the type of core material.
Which change will most likely increase the strength of a magnetic field produced by an electromagnet?
Add a battery
State two methods of increaseing the strength of the magnetic field?
Add another magnet. If an electromagnet increase the windings and/or the power applied. Raise the voltage applied and you will raise the magnetic flux.
How do you make a electromagnet stronger?
For a simple copper wire around iron nail electromagnet, increasing the number of rounds the copper wire makes around the nail will increase the electromagnet's strength. Also, increasing the voltage applied(adding a battery) will increase the magnetic field.
How does the number of wraps of wire affect the strength of an electromagnet?
The more turns of wire in an electromagnet the stronger the magnetic field.

What happens if you increase the current in an electomagnet?
As current increases, the electromagnet strength will increase.
Does the number of coil of wire in an electromagnet affect its magnetic strength?
yes,the more the coils the more the strength it collects
What happens when you add more coils to the wire in an electromagnet what else can you do to increase the magnetic field of an electromagnet?
The more loops gives the magnet more voltage. More loops produce more currents. The current that is induced as acts like an opposing magnet and makes it more difficult to move the magnet.
Two ways to increase the strength of an electromagnet?
-- Increase the current (amperes) flowing through the coil of wire that surrounds the electromagnet. -- Increase the number of 'turns' of wire in the coil.
What happens to the strength of magnetic force in an electromagnet when increasing the current through the coil?
The strength is increased, this is how Roller Coasters operate.
Why is the strength of an electromagnet so much greater than the strength of a solenoid's magnetic field?
