The following statements are related to the force of a magnetic field on a current-carrying wire. Indicate whether each statement is true or false. 1) The magnetic force on the wire is independent of the direction of the current.
A) True
B) False
2) The force on the wire is directed perpendicular to both the wire and the magnetic field.
A) True
B) False
3) The force takes its largest value when the magnetic field is parallel to the wire.
A) True
B) False

1) B: False

2) A: True

3) B: False

Explanation:

1) Statement is false because the force is not independent of the current but rather depends on the direction of the field and current.

2) Statement is true as per right hand thumb rule.

3) The statement is false because force takes its largest value when the magnetic field direction and electric current direction are perpendicular to each other.

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
