Passing an electric current through a wire will produce an external magnetic field.
This is because the electrons have spin and this spin is what produces the field.
Spinning electrons (of certain characteristics) also produce the magnetic field of permanent magnets.
And no spinning electrons, no magnetic field.
Magnetic field.
Yes, for as long as the magnetic field is moving along the conductor. A static magnetic field will not induce current, a dynamic field is required.
Not true - Moving a wire through a magnetic field doescreate a current flow in a wire.false
The direction of the magnetic field is counterclockwise or clockwise. For a current flowing in a wire you can use the "left hand rule" If you take your left hand and have the thumb point in direction of electron flow in the wire, the fingers wrapped around the wire will show the direction of the magnetic field by the direction the fingers are pointed..
The combination of the magnetic field of a coiled wire wrapped around an iron core will create a very useful electromagnet. This is the bases used in the construction of mechanical relays.
Current flows through a wire and produces a magnetic field.
the magnetic field around the adjacent pairs of wire
When electricity flows through a wire, it creates a magnetic field around the wire. This is because the moving electric charges generate a force that causes the magnetic field to form.
Eiectricity flows through wire not around the magnetic field.
Magnetic field.
increase the strenght of the magnetic field. :)
The magnetic field around a wire is determined by the direction of the current flow. If the current running in the wire is in the reverse direction, the magnetic field around the wire will also be reversed. The direction of the magnetic field is determined by the right-hand rule, where if you wrap your right hand around the wire with your thumb pointing in the direction of the current, your fingers will point in the direction of the magnetic field.
Inserting a material with a high magnetic permeability around the wire or reducing the current flowing through the wire would decrease the magnetic field around the wire.
Yes, a wire with no current flowing through it does not produce a magnetic field. Current flow is required to generate a magnetic field around a wire.
When a current-carrying wire is placed in a magnetic field, a force is exerted on the wire due to the interaction between the magnetic field and the electric current. This force causes the wire to move or experience a deflection, depending on the orientation of the wire and the magnetic field.
The direction and amplitude of the magnetic field around a wire depend on the direction and amplitude of the current through the wire. When the wire carries DC, the direction and amplitude of the current in the wire are constant, so the direction and amplitude of the magnetic field around the wire are constant. When the wire carries AC, the direction of the current in the wire is periodically reversing and its amplitude typically changes, so the direction of the magnetic field around the wire is periodically reversing and its amplitude is typically changing.
When the direction of the current in a wire is reversed in a magnetic field, the direction of the force acting on the wire also reverses. This causes the wire to move in the opposite direction within the magnetic field.
