Question

A straight vertical wire carries a current of 1.0 A into the page in a region where the magnetic field strength is 0.60 T. What is the magnitude and direction of the magnetic force on a 1.0 cm section of this wire if the magnetic field direction is toward the east

Answer 1

force on the wire of section cm will be
`6* 10^(-3)N`

Direction of force on the wire will be in south direction

Step-by-step explanation:

We have given current in the wire i = 1 A

Magnetic field strength B = 0.6 T

We have to find the force on 1 cm section of the wire so l = 1 cm = 0.01 m

Force on the wire containing current is equal to

`F=iBL`

`F=1* 0.6* 0.01=6* 10^(-3)N`

So force on the wire of section cm will be
`6* 10^(-3)N`

Direction of force on the wire will be in south direction
