Hello need help with part b

You are performing studies of the possibility of migrating birds using the Earth's magnetic field for navigation. To modify the magnetic field in the brain of a bird, you fit the bird with coils as "caps" and "collars" as shown in the t The data on the coils indicate that they each have 210 0 of resistance, a radius of 1.10 cm, and 50 turns of wire. The centers of the coils are separated by 2.35 cm. You wish to create an "Earth-like" magnetic field of 6.0 x 10-5 axis between the coils. Given this data, you need to determine the voltage of the battery (in V) needed to power the coils.

You’re an electrical engineer designing an alternator (the gener-ator that charges a car’s battery). Mechanical engineers specify a 10-cm-diameter rotating coil, and you determine that you can fit 250 turns in this coil. To charge a 12-V battery, you need a peak output of 14 V when the alternator is rotating at 1200 rpm. What do you specify for the alternator’s magnetic field?

Niobium metal becomes a superconductor when cooled below 9 K. Its superconductivity is destroyed when the surface magnetic field exceeds 0.100 T. In the absence of any external magnetic field, determine the maximum current a 5.76-mm-diameter niobium wire can carry and remain superconducting. A

Q43.7 an electrician has a long conductive wire. it carries a current of I=2.00A. the electrician bends the wire to make a loop-arc shape (refer to image provided). the loop-arc shape has a total radius or r=10.0 cm. help the elctrician figure out the magnitude and direction of the magnetic feild at point P which is located at the center of the loop-arc.

Consider a 150 turn square loop of wire 17.5 cm on a side that carries a 46 A current in a 1.75 T field   a. What is the maximum torque on the loop of wire in N⋅m?  b.   What is the magnitude of the torque in N⋅m when the angle between the field and the normal to the plane of the loop θ is 9°?

You have a conductor that is 1.6 meters long that you attach to a 12 V battery. The wire has a resistance of 1.27 ohms. What magnetic field strength in microT would you measure 1.3 cm away from the wire?
