What are 3 ways to change characteristics of a magnetic field by an electric current?
By changing the magnitude of the current flowing through the conductor. By changing the direction of the current flow in the conductor. By changing the orientation or shape of the conductor carrying the current.
What shape can be drawn though a solenoid to determine the magnitude of its magnetic field?
A circular loop or coil can be drawn through a solenoid to determine the magnitude of its magnetic field. By measuring the induced current in the loop or coil, the strength of the magnetic field can be inferred using Ampere's law.
What does a changing magnetic field induce in a conductor?
A changing magnetic field induces an electric current in a conductor.
How can we use Lenz's Law to determine the direction of induced current in each case?
Lenz's Law states that the direction of the induced current in a circuit is such that it opposes the change in magnetic flux that caused it. By applying Lenz's Law, we can determine the direction of the induced current by considering the direction of the changing magnetic field and the direction of the induced current that would oppose that change.
How does a coil of wire create a electrical current?
By itself, it won't. To have an electrical current, you need a voltage. This voltage might be applied externally, or it might be induced by movement of the wire through a magnetic field (or by a changing magnetic field).

Why does a transformer require alternating current?
In order to induce voltage as an output, a changing magnetic field is needed. To create a changing magnetic field in the transformer a changing current and that is an alternating current.
What does a changing magnetic field induce in a conductor?
A changing magnetic field induces an electric current in a conductor.
What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field
What does a changing magnetic field induce?

the generation of a current by a changing magnetic feild
What is conductor magnitude force?
Conductor magnitude force refers to the force experienced by a current-carrying conductor placed in a magnetic field. This force is known as the Lorentz force and is perpendicular to both the direction of the current and the magnetic field. It can be calculated using the formula F = BIL, where B is the magnetic field strength, I is the current, and L is the length of the conductor in the magnetic field.
How can we increase the magnitude of the magnetic field of an electric magnet?
You can increase the magnitude of the magnetic field of an electromagnet by increasing the number of turns in the coil, increasing the current flowing through the coil, and using a ferromagnetic core material within the coil. These factors collectively enhance the strength of the magnetic field generated by the electromagnet.
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.
