When is the force on a current-carrying wire in a magnetic field at its strongest?
-when the current is at a 0-degree angle to the field
-when the current is at a 30-degree angle to the field
-when the current is at a 45-degree angle to the field
-when the current is at a 90-degree angle to the field

Respuesta :

its D -when the current is at a 90-degree angle to the field

Answer: The correct answer is 'when the current is at a 90-degree angle to the field'

Explanation:

The Force on a current carrying wire in a magnetic field is given by lorents Force:

[tex]F=BILsin\theta[/tex]

B= Magnetic Field in Tesla

I = Current in a wire in Ampere

L= Length of the wire in meters

[tex]\theta [/tex] = angle between the Vetor B and vector I in degrees.

[tex]F=BILsin90^o[/tex] (force will be maximum)

[tex]F=BILsin0^o[/tex] (force will be minimum)
