Walker, Halliday & Resnick β Magnetic Fields Due to Currents: Problem 43
43 A student makes a short electromagnet by winding 280 turns of wire around a wooden cylinder of diameter \( d = 5.0 \text{ cm} \). The coil is connected to a battery producing a current of \( 3.8 \text{ A} \) in the wire. (a) What is the magnitude of the magnetic dipole moment of this device? (b) At what axial distance \( z \gg d \) will the magnetic field have the magnitude \( 5.0 \text{ \mu T} \) (approximately one-tenth that of Earthβs magnetic field)?
π Solution Approach
Given: 43 A
Find: (a) What is the magnitude of the magnetic dipole moment of this; (b) At what axial distance \
