1) The force on the wire is 1.5 N
2) The force on the wire is zero
Explanation:
1)
The force experienced by a current-carrying wire in a magnetic field is given by
where
I is the current in the wire
L is the length of the wire
B is the magnetic flux density
is the angle between the direction of the wire and of the field
In this part of the problem we have
I = 10 A
L = 2 m
B = 0.15 T
Substituting, we find
2)
As before, the force experienced by the wire is
where
I is the current in the wire
L is the length of the wire
B is the magnetic flux density
is the angle between the direction of the wire and of the field
In this case, however, the angle between the wire and the field is
And therefore
which means that the wire does not experience any force. In fact, the force experienced by the wire is zero when the wire is parallel to the field (such as in this case) and maximum when the wire is perpendicular to the field.
