What statements describes the result of reversing the current in a current-carrying in a magnetic field?
When the current is reverted, the magnetic field will also be reverted.
Force on a current-carrying conductor?
When a current-carrying conductor is placed in a magnetic field, a force is exerted on the conductor due to the interaction between the magnetic field and the current. This force is known as the magnetic Lorentz force and its direction is perpendicular to both the magnetic field and the current flow. The magnitude of the force depends on the strength of the magnetic field, the current flowing through the conductor, and the length of the conductor exposed to the magnetic field.
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.
What happens with the energy associated to the magnetic field of a coil with electric current if the electric current is turned off?
The magnetic field or energy associated with the magnetic field will no longer be generated if the current is turned off.
Why steel becomes a permanent magnet after electric current is passed through it?
When an electric current passes through steel, it creates a magnetic field within the steel. This magnetic field aligns the magnetic domains in the steel, causing it to become a permanent magnet. The alignment of the magnetic domains allows the steel to retain its magnetism even after the electric current is removed.
What is magnetization current?
There is no magnetic current because there are no magnetic charges.
What is the direction of the magnetic force on the current in (a)?
The direction of the magnetic force on the current in (a) is perpendicular to both the direction of the current and the direction of the magnetic field.
What is an electrical current that produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.

The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
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 when the current is doubled in a magnetic system?
Doubling the current in a magnetic system will result in the magnetic field strength doubling as well. This increase in the magnetic field can cause a proportional increase in the magnetic force experienced by a nearby magnetic material or particle. Therefore, the magnetic effects in the system will be stronger when the current is doubled.
Does electric current create magnetic fields?
Yes, electric current does create magnetic fields
How is the torque on a loop of current in a magnetic field determined when considering the interactions between the magnetic field and the current loop?
The torque on a loop of current in a magnetic field is determined by the interactions between the magnetic field and the current loop. This torque is calculated using the formula x B, where is the torque, is the magnetic moment of the loop, and B is the magnetic field strength. The direction of the torque is perpendicular to both the magnetic moment and the magnetic field.

Why can an electric current create a magnetic field?
An electric current creates a magnetic field because moving charges generate a magnetic field around them according to the right-hand rule. This magnetic field is perpendicular to both the direction of the current and the surrounding space. The strength of the magnetic field is dependent on the magnitude of the current.
Why do the magnetic forces acting on the coil change as the current running through the coil changes?
The magnetic forces acting on the coil change with the current because the strength of the magnetic field produced by the current in the coil is directly proportional to the current flowing through it. As the current changes, the magnetic field strength changes, leading to a change in the magnetic forces acting on the coil.
