What can induce an electrical current in a wire?
A magnetic field can induce an electrical current in a wire.
Can electrical current exert a magnetic force?
yes
How does a coil of wire create a electrical current?
By itself, it won't. To have an electrical current, you need a voltage. This voltage might be applied externally, or it might be induced by movement of the wire through a magnetic field (or by a changing magnetic field).
What is a temporary magnet produced using an electrical current?
An electric current produces a magnetic field.
When a wire with a current is placed on a magnetic field is electrical energy is transformed into mechanical energy?
True.
What can induce an electrical current in a wire?
A magnetic field can induce an electrical current in a wire.
What is an electrical current that produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
What is evidence that an electrical current produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
Can electrical current exert a magnetic force?
yes
What does a changing magnetic field induce?
An electrical current.
How is electricity made into magnetic effects?
Any time a current flows, any time an electrical charge moves, it is surrounded by a magnetic field. Several devices made by humans make use of this effect.
What type of energy is associated with an electrical current?
Magnetic Energy
What is an electrical current and what causes it?
Electrical current is nothing but movement of electrons in case of metals. It causes heating and produces magnetic field.
What are the effects of electric current?
current has five effects. 1. physical effects 2. xray effects 3. heating effects 4. chemical effects 5.magnetic effects.
How can you reverse the direction of the magnetic field in a wire produced by an electric current?
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.
Does the magnetic field increase or decrease if the current is decreased?
An increase in an electrical current will cause magnetism to increase but a decrease in an electrical current will cause magnetism to decrease.
What electrical principle is used in a magnetic breaker?
megnetic field and current
