The right-hand rule is a way to determine the direction of the magnetic field produced by moving charges. Imagine wrapping your right hand around the path of the charges so that the positive charges (or the current) flow from the little finger side of your fist to the thumb side (Figure 8.53). Then your fingers circle the path in the same direction as the magnetic field lines. Use this rule to verify the directions of the magnetic fields shown in Figures 8.8 and 8.10. How would you use the rule to find the direction of the magnetic field lines around a moving negative charge?

- In Niels Bohr’s 1913 model of the hydrogen atom, the single electron is in a circular orbit of radius 5.29 × 10−11 m and its speed is 2.19 × 106 m/s. (a) What is the magnitude of the magnetic moment due to the electron’s motion? (b) If the electron moves in a horizontal circle, counterclockwise as seen from above, what is the direction of this magnetic moment vector?arrow_forwardAn electron in a TV CRT moves with a speed of 6.0107 m/s, in a direction perpendicular to Earth's field, which has a strength of 5.0105 T. (a) What strength electric field must be applied perpendicular to the Earth’s field to make the election moves in a straight line? (b) If this is done between plates separated by 1.00 cm, what is the voltage applied? (Note that TVs are usually surrounded by a ferromagnetic material to shield against external magnetic fields and avoid the need for such a collection,)arrow_forwardThe magnetic dipole moment of the iron atom is about 2.11023Am2 .

If both wires carry a current I, how far apart must then parallel sections be so that the net magnetic field at P is zero?

The rectangle has length L = 2 meters, width w = 2 meters, and a resistance of R = 7.97 Ω. The magnetic field varies with time according to the equation:B(t) = 5t2 + 2t5As a result of the varying field, a voltage and current will be established in the loop.Answer all of the following: What is the FORMULA for the rate of change of magnetic field with time, dB dt = What is the FORMULA for the rate of change of magnetic flux with time, dΦB dt = What is the voltage in the circuit at t=1.1 seconds? Volts What is the current in the circuit at this same time? Amps NOTE: Make all formulas POSITIVE (field and flux). Make all values POSITIVE (voltage and current). Format your equations as atn + btm where a,b,n,m are numerical values.

In the design shown, ions are accelerated through a potential difference, V, after which they enter a region containing a uniform magnetic field. They describe semi-circular paths in the magnetic field and land on a detector a lateral distance x from where they entered the field region, as shown. Assume that there is no magnetic field in the accelerating region of the initial electric field, and no electric field in the semicircular path region. With the situation shown in Figure 5, are the ionspositively or negatively charged? Clearly explain yourreasoning.arrow_forward
