Answer:
a
The magnitude of the force is
The direction is from south to north i.e upward
b
The magnitude of the force is
The direction is towards the west
c
The magnitude of the force is
the direction of the magnetic field is parallel to the direction of the current (south to north ) hence the direction in 0 in comparison to the direction of the current
d
From the value of force we got the answer to this question is No
Explanation:
Generally magnetic force is mathematically represented as
Where the B is the magnitude of the magnetic field which is given as
is the current with a value of
L is the length of the wire given as
Substituting the value
For the first case where the current is moving from west to east and we are told that the magnetic field is from south to north the according to Fleming's right hand rule the force(exerted by earths magnetic field ) would be moving from south to north (i.e upward)
For the second case where current is moving vertically upwards the direction of the force is to the west according to Fleming's right hand rule
