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.

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.
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.
What is the A magnet that has coils of ccurrent-carrying wire around an iron core?
The current produces the magnetic field; such a magnet is called an electromagnet.
How is an electromagnet different from a regular bar magnet?
An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.
How is electromagnet the same as permanent?
An electromagnet is only magnetic while current is flowing through the coils. A permanent magnet is always magnetic, and does not need electricity. An example of an electromagnet at work is in a metal scrape yard, where a large electromagnet is used by a crane operator to lift ferrous metals into a crusher (scrapped cars, for instance). The metal drops into the crusher when the electricity is switched off by the crane operator. Therefore, they are only really similar when both are magnetised.
In an electromagnet the magnetic force increase as increase?
Adding more coils will make the magnetic field stronger. Magnetic field increases.
What effect does increasing the number of coils have on an electromagnet?
Adding more coils will make the magnetic field stronger. Magnetic field increases.
What happens to an electromagnet when electricity runs through it?
When an electric pulse runs through an electromagnet, the current travels in the electromagnets coils, causing a magnetic field to be developed inside and outside of the coils. The amount of coils, tightness of the coils, and the space between the coils are all very important factors in the production of said EM 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

How do you make an electromagnet weak?
reducing the number of coils around the core or by reducing the current in an electromagnet, will cause the magnetic power to weaken.
Is you true the magnetic field around an electromagnet can be made stronger by increasing current or decreasing the number of coils around the iron core?
No, you is false. Increasing current does it, but the number of turns in the coilalso must increase if you want to increase the magnetic field that way.
Would spinning the loops on an electromagnet make it stronger?
Yes, if you increase the number of coils or loops in an electromagnet, it's power increases.
Why does the strength of the electromagnet increase from the coils?
The electromagnet is made stronger in proportion to the current given. Refer to the link provided for more information.AnswerWhen current passes through the coil of wire surrounding the core of an electromagnet, it acts to align the magnetic domains within that core. Once all the domains have been aligned, the electromagnet has reached 'saturation' and is as strong as it can get. So the strength of an electromagnet is NOT proportional to its magnetising current.
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 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.
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.
