Why is iron nail used to make an electromagnet?
because exhibits maximum flux density requires small magnetising field exhibits low hysteresis loop
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.
Would increasing the length of a rod in an electromagnet increase it's magnetism?
No, as in this case,the rod is the magnet,and the strength of a magnet does not depend on its size.
What does not affect the strength of an electromagnet?
a donut
What has a wire-wrapped core?
A coil of wire or a coil in the shape of a cylinder is a typical shape for an electromagnet (or a solenoid). The strength of the magnetic field of an electromagnet can be increased significantly if the coil is wrapped around an iron core. This configuration may be called an inductor when used as an element of an electrical circuit.
Which change will most likely increase the strength of a magnetic field produced by an electromagnet?
Add a battery
What happens if you increase the current in an electomagnet?
As current increases, the electromagnet strength will increase.
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 do you increase electromagnetic field?
by increasing the power of electromagnet
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.
Is there more than one way to increase the strength of an electromagnet?
Yes
Is there more than one way to increase the strength of electromagnet?
Yes
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.
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 is iron nail used to make an electromagnet?

Why is the strength of an electromagnet so much greater than the strength of a solenoid's magnetic field?
hi how are you to day? hi how are you to day?
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.
