How far from the wire would a homing pigeon have to be so the field due to the wire has magnitude 50.0 μT, which is comparable to Earth’s magnetic field at the surface?A square loop of wire is 5.0 cm on a side. It carries a current of 2.0 Amps and is perpendicular to a magnetic field with a strength of 3000 T. What is the magnitude of the torque on the loop in Newton-meters?Neurons in our bodies carry weak currents that produce detectable magnetic fields. A technique called magnetoencephalography, or MEG, is used to study electrical activity in the brain using this concept. This technique is capable of detecting magnetic fields as weak as 1.0 x 10-15 T. Model the neuron as a long wire carrying a current and find the current it must carry to produce a field of this magnitude at a distance of 4.5 cm from the neuron. A
