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.
How do you make a electric magnet?
An electric magnet (or as it is more usually called, an electromagnet) requires a core, composed of a piece of iron or any other ferro-magnetic metal, and a wire wrapped around the core, normally in many windings (for greater magnetic strength) all going in the same direction (e.g., clockwise). When a current flows through the wire, the metal core will produce a magnetic field.
Is an electromagnet made of a coiled wire and a metal bolt stronger than one made with a wire alone?
Yes. An Iron core electromagnet has a stronger magnetic field then a coil. The magnetic flux is condensed and travels through the iron core with little resistance, while air provides much greater resistance.

How do you make a super power full electromagnet?
-- 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.
What are two ways to make the magnetic field of an electromagnet stronger?
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.
Which one is greater yield strength or breaking strength?
The breaking strength is always greater than the yield strength.
In what way did the Allies hold an advantage over the Central powers?
The Allies had greater miltary strength and size.
The magnetic field strength inside a current-carrying coil will be greater if the coil encloses a?
If the coil encloses an iron rod, then the magnetic field strength inside a current-carrying coil will be increased. This occurs because the air path in the coil is made shorter by putting in the rod. This in turn causes an increase in the field.
How are energy and wavelength of electromagnet radiation related?
The greater the energy the shorter the wavelength.
