Magnetic resonance imaging (MRI) scans are often prohibited for patients with an implanted device, such as a pacemaker. There are multiple reasons for this prohibition. One reason is the physical torque on the device due to the MRI's magnetic field. Suppose a patient's pacemaker implant requires I = 2.7 mA of current to function. The leads of the device travel close together until they reach the heart and then split off to touch the top and bottom of the heart, such that size of the current loop is approximately half the cross-sectional area of the heart. Suppose the MRI machine uses a magnetic field of B = 1.1 T. Treating the heart as a box that is L = 11.0 cm long and W = 8.0 cm wide, calculate the magnitude of the maximum torque t on the current loop. T= 2.376 ×10 Incorrect -5 N-m

Fast pls solve this question correctly in 5 min pls I will give u like for sure A long cable of circular cross section and diameter 2 cm has a long cylindrical hole of diameter 1 mm drilled in it parallel to the cable axis. The distance be- tween the axis of the hole and the cable axis is 5 mm. If the cable has a uniform steady current density of 10^5 A · m−2 flowing through it, calculate the magnetic field at the centre of the cable. (Hint: use the principle of superposition.)
