The direction of a magnetic field produced by an electric current depends on the direction of the what?
The direction of a magnetic field produced by an electric current depends on the direction of the current flow. The magnetic field will form circular loops around the current-carrying wire, following the right-hand rule.
The operation of an electric motor depends on?
The operation of an electric motor depends on the interaction of magnetic fields, passing of electric current through coils of wire (armature), and the resulting electromagnetic forces that cause the motor to rotate. The direction of the current and the arrangement of the magnetic fields determine the direction of the rotation, while the flow of current and the strength of the magnetic fields dictate the speed and torque of the motor.
What does the direction of the magnetic field depend on?
The direction of the magnetic field depends on the direction of the flow of electric charges. It follows the right-hand rule, where the thumb represents the current flow and the fingers represent the direction of the magnetic field lines.
What conditions are necessary for magnetic field to produce a force on a wire?
A current has to flow in the circuit to induce a force on the circuit
Why electromagnets work?
Electromagnets work by running an electric current through a coil of wire, creating a magnetic field. This magnetic field can attract or repel other magnetic materials, allowing electromagnets to be used in a variety of applications such as electric motors, relays, and speakers. The strength of the magnetic field can be controlled by adjusting the amount of current running through the wire.

Why a current wire deflects a magnetic needle placed near it?
When current flows through a wire, it creates a magnetic field around the wire. This magnetic field interacts with the magnetic field of the needle, causing the needle to deflect. The direction of deflection depends on the direction of the current and the orientation of the needle.
Why and when does a current carrying conductor kept in a magnetic field experiences a force list factor on which the direction of this force depend State the rule which may be used to determine the di?
A current-carrying conductor in a magnetic field experiences a force due to the interaction between the magnetic field and the current. The direction of this force depends on the direction of the current in the conductor and the direction of the magnetic field. The rule that can be used to determine the direction of the force is the right-hand rule, where the thumb points in the direction of the current and the fingers point in the direction of the magnetic field, indicating the direction of the force.
What must happen in order electric charges to produce a magnetic field?
Electric charges must be in motion to produce a magnetic field. When electric charges move, they generate a magnetic field around them. The strength of the magnetic field depends on the speed and direction of the moving charges.
How do you know that a force is negative or positive in relation to magnetic field?
The direction of a force acting on a charged particle in a magnetic field is determined by the right-hand rule. If the force is in the same direction as the magnetic field, it is positive; if it is in the opposite direction, it is negative.
What direction is a force exerted on the wire?
The direction of the force on a wire is perpendicular to the direction of the current flowing through the wire and to the direction of the magnetic field in which the wire is placed. This is described by the right-hand rule for magnetic fields.
What are 2 ex. of how electricity and magnetism are interrelated?
When an electric current flows through a conductor, it creates a magnetic field around the conductor, demonstrating the interrelation between electricity and magnetism. Conversely, a changing magnetic field around a conductor can induce an electric current in the conductor, illustrating how electricity and magnetism are interconnected through electromagnetic induction.
