Respuesta :

Explanation:

The magnetic force acting on a current carrying wire in a uniform magnetic field is given by :

[tex]F=I(L\times B)[/tex]

or

[tex]F=ILB\ sin\theta[/tex]

Where

[tex]\theta[/tex] is the angle between length and the magnetic field

The magnetic force is perpendicular to both current and magnetic field. It is maximum when it is perpendicular to both current and magnetic field.

So, the correct options are :

  1. The magnetic force on the current-carrying wire is strongest when the current is perpendicular to the magnetic field lines.
  2. .The direction of the magnetic force acting on a current-carrying wire in a uniform magnetic field is perpendicular to the direction of the field.
  3. The direction of the magnetic force acting on a current-carrying wire in a uniform magnetic field is perpendicular to the direction of the current.
