Tbelow is a net torque on the magnet in a counterclockwise direction.In a uniform field, the magnet experiences a net torque that often tends to align the north pole in the direction of the magnetic field.
Two concentric loops of wire are delivering currental fees in opposite directions as displayed in (Figure 2) . Describe the net force and also the torque on either of the existing loops.
Tbelow is a net pressure on each loop that causes them to repel each other.The loops produce magnetic fields in oppowebsite directions, comparable to what happens when 2 bar magnets are arranged with their north poles close to each other
If the bar magnet is flipped over and also the southern pole is carried close to the hanging ball, the sphere will certainly be
The magnetic dipole minute (μ) of a coil relies on the present (I), the location of the coil (A), and the number of loops (N). Rank the 3 various coils of wire shown in (Figure 3) in order by the magnitude of their magnetic dipole moment.
All same: 60!!The magnetic dipole moment (μ) is proportional to the area of the loop (A), the existing (I), and also the variety of coils (N). So, all three instances have actually the exact same magnetic dipole minute.Coil 2 = single coil with location 20cm2 and also I=3A.Coil 2 = single coil via area 20; m cm^2 and also I = 3; m A.Coil 1 = single coil via location 10cm2 and I=6A.Coil 1 = single coil with location 10; m cm^2 and also I = 6; m A.Coil 3 = coil via 6 loops each with a space of 10cm2 and I=1A
The torque (τ) that is exerted on a magnetic dipole moment (μ) counts on the orientation of the magnetic dipole minute. Rank the three loops of wire transferring existing displayed in (Figure 4) in order by the magnitude of the torque exerted on them.
