What statement describes the result of reversing the current in a current carrying wire in a magnetic field?
Reversing the current in a current-carrying wire in a magnetic field will reverse the direction of the force experienced by the wire. This is in accordance with Fleming's left-hand rule, where the thumb represents the current, index finger is the magnetic field, and middle finger indicates the force direction.

What terms correctly describes the shape of the magnetic field around a long straight current-carrying wire?
The shape of the magnetic field around a long straight current-carrying wire is generally described as concentric circles perpendicular to the wire.
Describes what happens when hold a compass close to wire carrying current?
When a compass is held close to a wire carrying current, the magnetic field created by the current induces a magnetic field around the wire. The compass aligns with this magnetic field and its needle will deflect in a direction perpendicular to the wire. This can be used to determine the direction of the current flow in the wire.
How does a magnetic field impact a current-carrying wire?
A magnetic field can exert a force on a current-carrying wire, causing it to move or experience a torque. This is known as the magnetic force on a current-carrying conductor, according to the right-hand rule.
In what direction is a force exerted on a current-carrying wire when it is placed in a magnetic field?
The force exerted on a current-carrying wire placed in a magnetic field is perpendicular to both the direction of the current and the magnetic field.
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.

When a magnetic field is parallel to a current-carrying wire what is the force on the wire?
When a magnetic field is parallel to a current-carrying wire, there is no force acting on the wire. This is because the magnetic force on a current-carrying wire is perpendicular to both the current and the magnetic field.
When is the force experienced by current carrying conductor placed in a magnetic field strongest?
The force experienced by a current-carrying conductor in a magnetic field is strongest when the current and magnetic field are perpendicular to each other, maximizing the force according to the right-hand rule.
