What is the magnetic field around a wire when the current running in the wire is in reverse direction?
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.
What happens to the direction of a magnetic field around an electric current when the direction of the current is reversed?
The direction of the magnetic field around the electric current also reverses when the direction of the current is reversed. This is determined by the right-hand rule, where the direction of the magnetic field is perpendicular to the direction of the current flow.
What is the direction of the magnetic field around a current-carrying wire?
The magnetic field around a current-carrying wire is circular and perpendicular to the direction of the current flow.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The magnetic field direction around the wire reverses when the direction of the current in the wire is changed. This is due to the right-hand rule that states the direction of the magnetic field is perpendicular to the direction of current flow.
What does a magnetic field look like around a current carrying a wire?
Around a current-carrying wire, the magnetic field forms concentric circles perpendicular to the wire. The strength of the magnetic field decreases as you move away from the wire. The magnetic field direction follows the right-hand rule where your thumb points in the direction of the current and your fingers show the direction of the magnetic field.
Name two deviceswhich use currentcarrying conductor and magnetic field?
Electric motor and loud speakers are the two devices that uses current carrying conductor and magnetic field.

How is a magnetic field around a straight piece of wire?
When current flows through a straight wire, a magnetic field is generated around the wire. The direction of the magnetic field can be determined using the right-hand rule: if you wrap your right hand around the wire with your thumb pointing in the direction of the current flow, your fingers will curl in the direction of the magnetic field lines.
What is the difference in the direction of the magnetic field produced around conductor by dc flow and ac flow?
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.
Effect on the magnetic field when the direction of current is reversed true or false?
True. When the direction of the current is reversed, the direction of the magnetic field also reverses. This is in accordance with the right-hand rule for determining the direction of the magnetic field around a current-carrying conductor.
What methods can be used for finding the direction of a magnetic field?
There are several methods that can be used to find the direction of a magnetic field. One common method is to use a compass, which aligns with the magnetic field lines. Another method is to use a magnetic field sensor or a magnetometer, which can detect the strength and direction of the magnetic field. Additionally, the right-hand rule can be used to determine the direction of the magnetic field around a current-carrying wire.
How do you use the right hand rule to determine the direction of a magnetic field around a current-carrying wire?
To determine the direction of a magnetic field around a current-carrying wire using the right-hand rule, point your thumb in the direction of the current flow and curl your fingers. The direction your fingers curl represents the direction of the magnetic field around the wire.
How does the right hand rule work to determine the direction of a magnetic field around a current-carrying conductor?
The right-hand rule is a way to determine the direction of a magnetic field around a current-carrying conductor. Point your thumb in the direction of the current flow, and curl your fingers. The direction your fingers curl represents the direction of the magnetic field around the conductor.
