Answer:
a) F =
b) attached below
c) 0.037 m/s
Explanation:
<u>a) Determine the magnetic "drag" force acting at the moment </u>
speed = v
first step: determine current in the loop
I = ----- ( 1 )
given that the current will induce force on the three sides of the loop found in the magnetic field
forces on vertical sides = + opposite
we will cancel out
hence equation 1 becomes
F = ( according to Lenz law we can say that the direction of force is upwards and this force will slow down the decrease in flux )
<u>b) Determine the formula for Vt</u>
attached below
<u>c) Find Vt </u>
given :
B = 0.80 T
density of copper = 8.9 * 10^3 kg/m^3
resistivity of copper = 1.68 * 10^-8 Ωm
∴ Vt = 16 ( 8.9 * 10^3 kg/m^3 ) ( 1.68 * 10^-8 Ωm ) ( 9.8 m/s^2 ) / ( 0.08 T)^2
= 0.037 m/s
