What is a temporary magnet made using electric current usually running around a metal core?
An electromagnet is a temporary magnet made using electric current running around a metal core. The magnetic field can be turned on and off by controlling the flow of current. Electromagnets are commonly used in various applications such as electric motors, MRI machines, and speakers.

When does the electric current flow?
An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).
Is a electric current a flow of electricity?
The flow of electrons from a body at a higher voltage to one at a lower voltage is flow of current.
Explain the difference between permanent and electromagnetic magnets?
In an electric magnet there is an ordinary metal used which when you run a current through it, induces a magnetic field, the permanent magnet (usually made of lodestone) contains particles which are already arranged in a manner that produces a magnetic field.
Electric current is the continuous flow of atoms in a conductor. True or false?
False. Electric current is the flow of electric charge (usually carried by electrons) through a conductor, not the flow of atoms.
Does an electric current move a short distance and then stop?
No, an electric current flows continuously in a closed circuit. The movement of charges (usually electrons) through the conductor allows the flow of current to persist until the circuit is broken.
Is a battery a temporary source of electric current?
Yes. A generator is another temporary source, but it can usually be used more than once, so a battery would be the best choice.

What is a temporary indulgence?
Temporary Indulgence Temporary Indulgence is a grace period, usually 30 to 60 days, that may be granted to allow you to bring the mortgage current
What type of electric current is used in household?
Alternating electrical current is usually used in household.
Is a electric current a flow of electricity?
The flow of electrons from a body at a higher voltage to one at a lower voltage is flow of current.
Explain the difference between permanent and electromagnetic magnets?
In an electric magnet there is an ordinary metal used which when you run a current through it, induces a magnetic field, the permanent magnet (usually made of lodestone) contains particles which are already arranged in a manner that produces a magnetic field.
What is an electical current?
Electric current is simply the flow of free electrons in a conductor. It is usually defined as the rate of charge flow, because the free electrons represent an electric charge.
Electric current is the continuous flow of atoms in a conductor. True or false?
False. Electric current is the flow of electric charge (usually carried by electrons) through a conductor, not the flow of atoms.
What is a device that measures the strength of an electric current?
An ammeter is a device that measures the strength of an electric current. It is usually connected in series with the circuit where the current is to be measured and provides a reading in units of amperes.
What is the unit electric current?
Amp or ampere'Ampere', usually shortened to 'amp'.The Ampere
Which parameter causes death due to electric shock either the voltage or the current?
This is usually specified in terms of the current. But the current is caused by a voltage.
An electric current is made up of?
An electric current is made up electrons that are moving into a place that is usually positively charged. It moves towards an area that is positive to be able to neutralize that charge.
