Determine the magnetic flux through a square loop of side a if one side is parallel to, and a distance b from a straight wire that carries a current I.

1. If the loop is pulled away from the wire at speed v, what emf is induced in it?

2. Which way does the induced current flow through the loop?

3. How does the emf vary in time, if the initial position of the left vertical side was b0 at time t=0?

4. Determine the force F required to pull the loop away from the line of current.

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

a=d/t

a="triangle"v/t

explanation:

a = acceleration
