Is a solenoid a coil of wire that has a current?
YESA solenoid is a coil of wire, which turns into a magnet when a?current?flows through
How can you use a solenoid to make a temporal magnet?
Passing it through a coil that has a DC current through it. The DC current creates a field which allows the realignment of electrons in the solenoid, allowing it to have temporary magnetic properties. Passing an AC current through the coil would demagnetize the solenoid.
Can a solenoid suspended by a string be used as a compass?
A solenoid can be used as a compass when a DC current is going through it because when a current is going through the solenoid, the magnetic field lines are nearly uniform and perfectly parallel inside of it, giving it essentially a north pole and south pole.
What is the difference between electromagnet and solenoid?
A solenoid is a coiled wire with an electric current running through it, causing a magnetic field. An electromagnet is almost the same thing except it is much stronger than a solenoid (usually) and, unlike a solenoid, has a soft, iron core.
How is a solenoid similar to a magnet?
A solenoid acts like a magnet when an electrical current is sent through the coil. A permanent magnet is magnetic all the time. Therefore, they are similar when both act like a magnet, but not when the solenoid is turned off.

Which factors affect the magnetic strength of a solenoid which is carrying an electric current?
Factors affecting the magnetic field strength of a solenoid are: - length of the solenoid - diameter of the solenoid - current through the coil around the solenoid - number of turns of the coil of current around the solenoid, usually turns of wire - material in the core
What if a current passes through solenoid If yes then what happens in the whole process?
Yes. DC can pass through. As it passes through then solenoid would act as if a bar magnet.

What are solenoid?
The solenoid of an automobile is associated with the starter system and transfers an electric current into the starter motor to set the engine into operation. When the ignition key is turned, current is released from the battery and travels along an insulated wire into the solenoid. The solenoid then releases a small plunger that creates a connection between two internal electrical posts, sends the current down another wire to the starter and forces the starter motor to spin.In general, a solenoid is an electromagnet with a movable metal core. Any coil of wire with current flowing through it will induce a force moving perpendicular to the wire. In the case of a coil wrapped around a cylinder, this force would be directed along the length (through the center) of the cylinder. As such, if you place a movable ferromagnetic (such as iron, nickel, or cobalt) rod through the center of the coil, it will move when current is applied to the electromagnet. This allows a mechanical action to be controlled by the solenoid.
What changes an electoromagnets magnetic field?
the direction of current through the wires sorounding the solenoid
What happens if you turn off the electric current in the solenoid?
If you turn off the electric current in the solenoid, the solenoid quits pulling its armature.

What is the relationship between electricity and magnetism with an electromagnet?
Oesterd discovered that when an electric current flows through a conductor a magnetic field develops around the conductor. So when you switch on the electromagnet a current passes through a solenoid generating a magnetic field which can be controlled by either forming more or less loops or increasing/decreasing the amount of current passing through the solenoid.
What is made by passing an electric current through coils of wire?
An electro magnet is created when a current is passed through a coil of wire. This effect is the main operation of how an electrical solenoid operates.
How is a solenoid similar to a magnet?
A solenoid acts like a magnet when an electrical current is sent through the coil. A permanent magnet is magnetic all the time. Therefore, they are similar when both act like a magnet, but not when the solenoid is turned off.
