What is magnetic field produced by a current flowing through a wire?
A current flowing through a wire produces a magnetic field around the wire. The direction of the magnetic field is determined by the right-hand rule, where if you point your thumb in the direction of the current, your fingers will curl in the direction of the magnetic field lines. The strength of the magnetic field is directly proportional to the current flowing through the wire.
An electric current flowing through a wire gives rise to a magnetic field whose direction depends upon what of the current?
The direction of the magnetic field produced by an electric current flowing through a wire is dependent on the direction of the current. The right-hand rule can be used to determine the direction of the magnetic field relative to the direction of the current flow.
How do you reverse the direction of a magnetic field?
You can reverse the direction of a magnetic field by changing the direction of the electric current flowing through a conductor. This is known as the right-hand rule - if you pass your right-hand thumb in the direction of the current flow, your fingers will curl in the direction of the magnetic field. By reversing the direction of the current, you can reverse the direction of the magnetic field.
What is the strength and direction of the magnetic field outside of a solenoid?
The strength of the magnetic field outside of a solenoid is weak and the direction is similar to that of a bar magnet, flowing from the north pole to the south pole.
How do you reverse the magnetic field of an electromagnet?
To reverse the magnetic field of an electromagnet, you can either reverse the direction of the current flowing through the coil or change the polarity of the power supply connected to the coil. This will change the direction of the magnetic field produced by the electromagnet.

What is the right hand rule for determining the direction of a magnetic field when a current is flowing out of the page?
The right-hand rule states that if you point your right thumb in the direction of the current flow, your fingers will curl in the direction of the magnetic field.
Could a magnetic field be electrons flowing through power lines?
A magnetic field is caused by flowing currents, but the field lines are not directly related to the flow of electrons or other charged particles. They are simply an abstraction that tells you where the magnetic attraction is strongest, and in what direction it goes.
Do all metals respond to magnet?
Magnetism in metals is due to electrons flowing in the same direction, causing a magnetic field. Not all metals produce a magnetic field.
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..
What is the strength and direction of the magnetic field generated by a finite current-carrying wire?
The strength of the magnetic field generated by a finite current-carrying wire is directly proportional to the current flowing through the wire and inversely proportional to the distance from the wire. The direction of the magnetic field can be determined using the right-hand rule, where the thumb points in the direction of the current and the fingers curl in the direction of the magnetic field.
What is the effect on the direction of the compass needle when you close the circuit?
When you close the circuit, a magnetic field is produced which can deflect the compass needle. The direction of the compass needle will align with the magnetic field produced by the current flowing through the circuit.
How can the magnetic field of an object be increased?
The magnetic field of an object can be increased by increasing the number of magnetic domains aligned in the same direction, increasing the strength of the magnetic material used, or by increasing the current flowing through a wire in an electromagnet.
