Are conductors magnetic?
While not intrinsically magnetic necessarily, conducting current means a magnetic field is formed.
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).
How can magnets produce an electric current?
When a conducting material is moved through a magnetic field, a current starts to flow in the conductor. This is the principle of the electric generator.
Are conductors magnetic?
While not intrinsically magnetic necessarily, conducting current means a magnetic field is formed.
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.
Will magnetic field is produced when current is passed through a thick conducting sheet?
Yes,,,a current carrying conductor wil produce magnetic field around it.
Can electrical current exert a magnetic force?
yes
What does a changing magnetic field induce?
An electrical current.
What is noncunducting?
Something classed as non-conducting is a material that will not carry an electrical current.
Is an acid or base better at conducting an electrical current?
An acid, as bases are less likely to conduct electrical currents
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.
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.
