(a) What is the magnitude (in Tesla) of the magnetic field due to the infinite wire at the point P in the rectangular loop, a distance r=3.2 cm from the wire (see figure).
In which direction does it point?
(b) Calculate the magnitude of the magnetic flux (in Tesla m2) through the rectangular loop due to the magnetic field created by the infinite wire.
(c) Suppose the current in the infinite wire starts increasing in time according to I=bt, with b=50 Amps/sec. What is the magnitude (in Amps) of the induced current in the loop? Neglect any contribution to the magnetic flux through the loop due to the magnetic field created by the induced current.
(d) What is the direction of this current flow?
b) phi = (mu_0*I*L/(2*Pi))*ln(1+w/h)
c) i = (-1/R)*(mu_0*L)/(2*Pi)*ln(1+w/h)*(di/dt)
BTW - for C just use the value for b (the one in the question) b=(di/dt)

Please anyone 10 and 9c)
b)=(B*V*W)/R
c)=(B^2*V*W^2)/R
d)= (M*g*R)/(B^2*W^2)
Result of e multiplied by 2*pi*b*d
t*s^2/(2*PI^2*(b^2-a^2) )
Is this correct?
t*s^2/(2*PI^2*b*(b^2-a^2) )
(t*s^2)/(2*PI^2*b*(b^2-a^2))
Please, anyone 9c) and 10c)

What is the total magnetic flux through the loop (in Tesla m ) when is 62 cm. Include only the magnetic flux associated with the external field (i.e. ignore the flux associated with the magnetic self-field generated by the current in the wire loop). Note that you do not need to calculate or know at what time the loop is at this location.
incorrect
(b) Using Faraday's Law and Ohm's Law, find the magnitude (in Amps) of the induced current in the bar at the time when 1.00 m/sec. Note that you do not need to calculate or know at what time the loop has this speed.
incorrect
(c) Which way does the current flow around the loop, clockwise or counterclockwise?
Status: correct
(d) What is the total magnetic force (in Newtons) on the rigid wire loop when 1.00 m/sec? Again, ignore any effects due to the self magnetic field.
direction:
Status: correct
magnitude (in Newtons):
incorrect
(e) What is the magnitude of the terminal speed (in m/sec) of the loop (i.e. the speed at which the loop will be moving when it no longer accelerates)?
poling vector = E*B/mu_0 = ??

pointing vector with formula E*B/mu_0, mu_0 = 4*pi*10^(-7), incorrect.
pliz, tell where is error?

What's wrong with this formula guys??
Please help?
for example s=24u and t=5u
s^2*t = 24*24*5*1u^3
P=1/3T * int(-L*w*(Imax)^2*sin(wt)*cos(wt), 0 , 3T)
Thanks!!!
at s=12uC/sec, t=1usec, b=0.0053m, a=0.0014m
I've followed the formula, but the answer shows wrong... I hope you guys can help?
(1u*12u^2)/(2*(PI^2)*5.3m*(5.3m^2-1.4m^2)*8.85e-12) =5.95215457341
E =|E|er
|E|=1/(4*pi*e_0*kappa)*q/r^2 for (a<r<b) |E|=1/(4*pi*e_0)*q/r^2 for r>=b

P=1/3T * int(-L*w*(Imax)^2*sin(wt)*cos(wt), 0 , 3T) = 0!!!!!
