How to increase magnetism an electromagnet

Electromagnets are composed of a conductive material arranged in a coil, often around a ferromagnetic core such as iron and steel. When an electrical current is transmitted through the coil, the electromagnet creates an electric field where ferromagnetic core increases. When the electrical power is off, the magnetic field disappears.

The size of the electric field depends on the size of the electric current and the voltage that the number of turns in the coil and the permeability of the ferromagnetic core. . Changing any or all of these will change the magnitude of the magnetic field.


You need 1 electromagnet

1.
Increase the electrical current through the electromagnet. Because power is equal to the square at the present time with the resistance of the material and the magnitude of the magnetic field is directly proportional to the current flowing through the electromagnet, field strength increases on the square of the increase in electricity into the electromagnet. This will remain faith until the electromagnet is saturated and the field strength flares out.

2.
Increase the number of turns in the coil. The magnitude of the magnetic field is directly proportional to the number of teeth in the electromagnet's coil, so adding double numbers of turns will double the field strength. Again, this will remain faith until the electromagnet reaches its saturation point and the field strength flares out.

3.
Change the ferromagnetic core of the electromagnet. The magnetic field strength is directly proportional to the permeability of core material, so a doubling of permeability will double the magnetic field strength --- up to the point where the material is saturated. Likewise, if the electromagnet currently has no kernel, adds you will increase its magnetic field strength.
Good advice and warnings

Increase the current in the electromagnet without increasing the electrical current used, is possible. Magnetic field strength is directly proportional to the size of the electric current, but resistor will reduce the amount of current that can pass through at any time. Cooling of the electromagnet will decrease its resistance, thus improving the current, which increases the power of the electromagnet.
High-strength magnetic fields are dangerous, and even deadly. Always be aware of the symptoms of dangerously high magnetic fields, such as dizziness and a metallic taste in the mouth.

As with all activities that involve electricity, disconnect power from power and any other source of electricity before making any adjustments to avoid the risk of electric shock.
