Question
1. The figure shows an end view oftwo wires carrying current. means that the direction of the current points into the page and means out of the page. What is the direction of the force that wire 1 exerts on wire 2? Please give detailed explanation. (5 ptsO 2. Refer to the figure in question 1. Is the direction of the magnetic field around wire 1 clockwise or counter Please give detailed explanation. (5 pts) 3. Two wires carrying equal currents exert a force Fo on each other. The current in each wire is doubled, while the distance of separation remaining constant. What is the magnitude of the force that one wire exerts on the other? When a magnetic field is parallel to a current-carrying wire, what is the force on the wire? Please give detailed explanation. (15 pts)Explanation / Answer
1) repulsive force.
we know, if the current paases opposite direction in two paralel wires they repel each other.
2)
wire 1 ---> counter clockwise
wire 2 ---> clockwise
use right hand rule:
take your right hand thumb finger in the direction of current and curl your fingers.
the curl of your fingers indictes the direction of magnetic field.
3)
we know, magnetic force between two wires, F = mue*I1*I2*L/(2*pi*d)
so, When I1 and I2 both are doubled, F becomes 4 times.
F = B*I*L*sin(theta)
when theta = 0 degrees, F 0
