What is the relationship between electron and magnetism?
Electrons have a charge. Any moving charge creates an electric field, e.g. electricity moving through a wire causes a magnetic field around the wire, or the earth rotating creates a magnetic field which causes a compass to point north. Similarly all electrons have a spin factor. similar to the earth rotating, the spin of electrons create a magnetic field around the electron.
Passing a magnetic field by a wire creates a what?
Passing a wire near a magnetic field induces an electric current in the wire.
What causes a magnetic field to be produced around a wire?
Current flows through a wire and produces a magnetic field.
How is mechanical force produced on a wire when it is passed through a wire in a magnetic field?
The movement through a magnetic field will induce a voltage; if there is a closed circuit, that will produce a current. The current, in turn, will have a magnetic field, which will interact with the external magnetic field. The direction of the interaction will be such that energy is conserved, i.e., it will tend to slow the wire down.
Does increasing current on a wire increase the magnetic force acting on it?
Yes, increasing the current in a wire will increase the magnetic force acting on it. This is described by the right-hand rule, where the direction of the magnetic force is perpendicular to both the current flow and the magnetic field. Increasing the current increases the strength of the magnetic field around the wire, leading to a stronger magnetic force.
Why does moving the magnetic field past the wire induce a voltage?
A good question. When an electron is moved, it will generate a magnetic force. In a permanent magnet, there are a 'magnetic domains' in which a number of electrons have similar spin direction. In an electromagnet, there are, by definition, a number of electrons moving in the same direction. If you do not have a moving electron, you do not have a magnetic field! From this statement, you may deduce that the amazing magnetic loops on the Sun, are generated by currents flowing inside the Sun.
What is the direction of the magnetic field if the current is directed upward or downward?
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..
Does a wire with no current have a magnetic field?
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.
What happens to the magnetic field if the current in the wire increases?
If the current in the wire increases, the magnetic field also increases.
Why does a current carrying wire deflect a magnetic compass?
A current-carrying wire generates a magnetic field around it due to the flow of electric charges. When the wire is placed near a magnetic compass, the magnetic field produced by the wire interacts with the magnetic field of the compass needle, causing the needle to deflect and align with the direction of the wire's magnetic field.
How is a current induced in a wire when a coil of wire moves through a magnetic field?
When a coil of wire moves through a magnetic field, the changing magnetic field induces a current in the wire through electromagnetic induction.
When you loop the wire with a current it will?
increase the strenght of the magnetic field. :)
Does electricity flow through wire or around its magnetic field?
Eiectricity flows through wire not around the magnetic field.
What happens to a current-carrying wire when placed in a magnetic field?
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.
What is produced around a wire that has a current?
Magnetic field.
What happens to a current carrying wire in a magnetic field when it is reversed?
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.
Why is the magnetic force on a wire at a maximum when the wire is perpendicular to the magnetic field?
When the wire is perpendicular to the magnetic field, the force on the moving charges in the wire is maximized because the magnetic field exerts a force perpendicular to both the field and the direction of current in the wire. This results in the maximum Lorentz force acting on the charges in the wire, leading to the maximum overall force experienced by the wire.
