Numerie A numeric value is expected and not an expression. Prabem 2: The magnctic ficld ofsproton is relativoly osc to that of cincular curent loop 8 850 10 m in Part (a) To see why an MRI utilizes iron to increase the magnetic field produced by a coil, calculate the current needed in a 400 loop-per-meter circular coil 0.660 m irn radius to produce a 1.20 T field (typical of an MRI instrument) at its center with no iron insert. Numeric A numeric value is expected and not an expression Part (b) What is the field at the center of a proton? Notice how it compares to the field we used in the previous calculation. Numeric :A numeric value is expected and not an expression. Fralen & A monmochanical water mcta could uc e all cfloct by applying a magnctic ficld along a tal pie and mcauring the Hal What is the average fluid velocity in m's for a 4.75 cm diameter pipe, if a 0.625 T field along it creates a 60.0 mV Hall voltage? Numerie A numeric value is expected and not an expression. Problem 4: An infinitely long wire carries a currentof - 195 AExplanation / Answer
F = mu0 I1 I2 L / 2 pi d
I2 = F * 2 pi * d / mu0 I1 L
= (3.5 * 2 pi * 5 * 10-2) / (4 pi * 10-7 * 1150 * 2.5)
magnitude of current = 304 A
