Chapter 18, Problem 1RQ

The presence of a magnetic force field may be detected by using

a. a compass.
b. iron filings.
c. a magnet.
d. all of the above.

Expert Solution & Answer

To determine

Find the right option.

Answer to Problem 1RQ

The right option is “d. all of the above”.

Explanation of Solution

The magnetic force is the force of attraction or repulsion which arises between the electrically charged particles because of its motion.

If the bar magnet is free to rotate, it will rotate until one end points to the south pole and other end points to the north pole, where the points are named as south-seeking and north-seeking pole. If the same poles of the two magnets are brought near, it creates repulsion. In general, same poles repel each other and opposite poles attract each other.

The presence of a magnetic force field may be detected by using:

(1) A compass.
(2) An Iron filing.
(3) A magnet.

A compass is a device which is structured as a small magnetic needle and it tends to rotate freely on the bearing. The compass device can detect the presence of the magnetic force field.

The magnetic field can also be found by using the iron filings. The iron filing is actually two-dimensional but the field around the magnet can be viewed as three-dimensional.

The magnetic force near the electric current or the magnetic pole can also be detected by using a magnet.

Therefore, the presence of a magnetic force field may be detected by using a compass, iron filings, and a magnet.

Conclusion:

Hence, the correct option is “d. all of the above”.

For each of the actions depicted below, a magnet and/or metal loop moves with velocity v→ (v→ is constant and has the same magnitude in all parts). Determine whether a current is induced in the metal loop. If so, indicate the direction of the current in the loop, either clockwise or counterclockwise when seen from the right of the loop. The axis of the magnet is lined up with the center of the loop. For the action depicted in (Figure 5), indicate the direction of the induced current in the loop (clockwise, counterclockwise or zero, when seen from the right of the loop). I know that the current is clockwise, I just dont understand why. Please fully explain why it's clockwise, Thank you

A planar double pendulum consists of two point masses \[m_1 = 1.00~\mathrm{kg}, \qquad m_2 = 1.00~\mathrm{kg}\]connected by massless, rigid rods of lengths \[L_1 = 1.00~\mathrm{m}, \qquad L_2 = 1.20~\mathrm{m}.\]The upper rod is hinged to a fixed pivot; gravity acts vertically downward with\[g = 9.81~\mathrm{m\,s^{-2}}.\]Define the generalized coordinates \(\theta_1,\theta_2\) as the angles each rod makes with thedownward vertical (positive anticlockwise, measured in radians unless stated otherwise).At \(t=0\) the system is released from rest with \[\theta_1(0)=120^{\circ}, \qquad\theta_2(0)=-10^{\circ}, \qquad\dot{\theta}_1(0)=\dot{\theta}_2(0)=0 .\]Using the exact nonlinear equations of motion (no small-angle or planar-pendulumapproximations) and assuming the rods never stretch or slip, determine the angle\(\theta_2\) at the instant\[t = 10.0~\mathrm{s}.\]Give the result in degrees, in the interval \((-180^{\circ},180^{\circ}]\).
