The magnetic force on a moving charged particle is always perpendicular to the magnetic fieldB→. Is the trajectory of a moving charged particle always perpendicular to the magnetic field lines? Explain your reasoning.

Short Answer

Expert verified

No, the trajectory of a moving charged particle always perpendicular to the magnetic field lines.

Step by step solution

01

Magnetic force on a moving charge

The magnetic field of force on a moving charge is perpendicular to the velocity and magnetic field of the charge which is given by the right-hand rule.

02

Step-2: Explanation

The particle will enter the magnetic field with a velocity that has a component parallel to the magnetic field, hence the component will remain unchanged and there will be a motion in the direction of the field. Hence, the trajectory of a moving charged particle will not always be perpendicular to the magnetic field lines.

Two coils are wound around the same cylindrical form. When the current in the first coil is decreasing at a rate of , the induced emf in the second coil has magnitude 1.65×10-3V. (a) What is the mutual inductance of the pair of coils? (b) If the second coil has 25 turns, what is the flux through each turn when the current in the first coil equals 1.20A? (c) If the current in the second coil increases at a rate of 0.360A/s, what is the magnitude of the induced emf in the first coil?

A 140-g ball containing excess electrons is dropped into a 110-m vertical shaft. At the bottom of the shaft, the ball suddenly enters a uniform horizontal magnetic field that has magnitude 0.300 T and direction from east to west. If air resistance is negligibly small, find the magnitude ond direction of the force that this magnetic field exerts on the ball just as it enters the field.

The potential difference across the terminals of a battery is 8.40 V when there is a current of 1.50 A in the battery from the negative to the positive terminal. When the current is 3.50 A in the reverse direction, the potential difference becomes10.20 V . (a) What is the internal resistance of the battery? (b) What is the emf of the battery?

In the circuit shown in Fig. E26.49, C = 5.90 mF, Ԑ = 28.0 V, and the emf has negligible resistance. Initially, the capacitor is uncharged and the switch S is in position 1. The switch is then moved to position 2 so that the capacitor begins to charge. (a) What will be the charge on the capacitor a long time after S is moved to position 2? (b) After S has been in position 2 for 3.00 ms, the charge on the capacitor is measured to be 110 mC What is the value of the resistance R? (c) How long after S is moved to position 2 will the charge on the capacitor be equal to 99.0% of the final value found in part (a)?
