Answer:
The value is
The direction is into the surface
Explanation:
From the question we are told that
The mass density is
The coefficient of kinetic friction is
The current the wire carries is
Generally the magnetic force acting on the wire is mathematically represented as
Here is the frictional force which is mathematically represented as
While is the magnetic force which is mathematically represented as
Here is the angle between the direction of the force and that of the current
So
So
=>
=>
=>
Apply the right hand curling rule , the thumb pointing towards that direction of the current we see that the direction of the magnetic field is into the surface as shown on the first uploaded image
