# What happens to the strength of an electromagnet as you increase the number of coils?

The energy of electromagnet will increase

### What makes electro magnets stronger?

You can change the strength of an electromagnet 3 ways. You can increase the amount of current (Amperes) running through your wire. You can increase the number of turns, or, if insulated, number of layers of turns on your wire coil. Last you can change the core - material, density, diameter, length.

### 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…

### What if you increase the current in a electromagnet?

Electromagnet is a device which works on the Fleming's left hand rule. The rule says that if a magnet, motion of current and direction of magnetic field are perpendicular to each other then the flowing causes motion in the coil.( due to the Lorentz's force). The rule states that the speed of the coil: * is directly proportional to the flow of current, i.e. more is the flow of current, more is the speed of…

### What is the significanse of increasing the number of turns on an electromagnetic coil?

As you increase the number of coils around an electromagnet, the magnetic field around the electromagnet gets stronger. As the electromagnet gets stronger it able to generate or convert more electricity and therefore this increases the efficiency rate of the transformer and hence the transformer is able to convert the voltages passing through it at a higher rate.

### How does the strength of a wooden core electromagnet compare with that of the iron core electromagnet?

Electromagnets consist of wire coiled around a core. The core can be anything from air to a nail or even a pencil. Since electrons flow freely through a conductive core (like a nail), an electromagnet made with a metal core will have a larger magnetic field (and thus be stronger) than an electromagnet with a wooden core. The strength of an electromagnet is related to the number of times the wire is coiled around the…
