Question

what magnetic field strength and direction will levitate the 2.0 g wire?. what should be the direction, into or out of the page?

Answer 1

The magnetic field strength and direction required to levitate a 2.0 g wire depend on the current flowing through the wire and the direction of the external magnetic field. The external magnetic field should be into the page to levitate the wire.

Step-by-step explanation:

The magnetic field strength and direction required to levitate a 2.0 g wire depend on the current flowing through the wire and the magnetic field created by that current. According to the right-hand rule, the direction of the magnetic field around a current-carrying wire is determined by curling your right fingers in the direction of the current, and your thumb will point in the direction of the magnetic field.

If the direction of the magnetic field created by the wire is into the page, to levitate the wire, the external magnetic field must have a direction opposite to the magnetic field created by the wire. If the external magnetic field is also into the page and its strength is greater than the magnetic field strength created by the wire, it will levitate the wire. However, if the external magnetic field is out of the page, it will not levitate the wire.

Answer 2

The magnetic field strength and direction required to levitate a 2.0 g wire depends on the current flowing through the wire and the direction of the magnetic field. Using the right-hand rule, the magnetic field should be directed in a specific way to levitate the wire.

Step-by-step explanation:

The magnetic field strength and direction that will levitate the 2.0 g wire depends on the current flowing through the wire and the magnetic field it is placed in. According to the right-hand rule, the magnetic field should be directed in a specific direction to levitate the wire. If the current is flowing into the page, then the magnetic field should be directed out of the page to levitate the wire. If the current is flowing out of the page, then the magnetic field should be directed into the page to levitate the wire.
