make an electromagnet stronger by doing these things: * wrapping the coil around an iron core * adding more turns to the coil * increasing the current flowing through the coil.
An electromagnet will maintain a charge as long as current continues to flow through it. Strengthening the charge is a matter of changing, or adjusting the components that enable the charge to flow. There are many ingredients that affect electromagnet strength. The length and width of the magnetic field, the amount of resistance the current encounters, the pulling power of the magnet itself, all determine how strong your electromagnet will be.
A loudspeaker contains a metal coil, known as an electromagnet, that creates a magnetic field when an electrical current passes through it. It is the action of the electromagnet that is responsible for converting electrical energy into audible sound.
It can, it just wouldn't be permiable.
The strength of the electromagnet depends on the magnitude of the current in the coil around it.The voltage required is only what produces the desired current in the coil. Since the coil is nothing butwire, the resistance is quite low, and a relatively small voltage produces a relatively large current.
An electrical current will cause an electromagnet to energise.

-- Use greater length of wire. -- Wind it into more turns around the coil. -- Decrease the diameter of the coil. -- Increase the electrical current through the coil. Each of these actions will increase the strength of the electromagnet.
by decreasing its current,by decreasing turns of coil
You can make an electromagnet stronger by increasing the number of loops in the coil or by passing more electricity through the coils or by chaging the core to a be replaced by a better conductor.
No. You should use a wire with the best electric conductivity (copper or silver) and wrap it around a (soft) iron core. The wire creates the magnetic field, the iron core concentrates it and turns into a magnet when a voltage is applied to the wire. Iron has rather poor conductivity and malleability so is not suited as the coil of an electromagnet.

* A conductor that can be shaped into a coil. Copper wire, for example. * An isolator that keeps the conductor's threads isolated from each other, thus forcing the current through all loops of the coil. * An electric current through the coil. * Typically, but not necessarily, a ferrite core to bundle the magnetic field.
No, the electromagnet is not made weaker by making the core larger. It can be made weaker by decreasing its current and/or turns of coil.
The two ways to increase the strength of a magnetic field of an electromagnet include increasing the current and increasing the number of wire revolutions around the iron bar. Having fewer windings weakens the electromagnetic strength.
