Maslowich

A magnetic field is experienced by the charged particle in the +y direction.

Discussion:

  • The right thumb rule states that the magnetic field lines will be perpendicular in the area to the conductive wire's left in which the electric potential is traveling.
  • The direction of the current may be determined by looking at the positive charge's (X direction) motion. According to Fleming's left-hand rule, the force on a positive charge will be in the +y direction because the positive charge is moving in a leftward direction, which will also be the direction of the current.

Fleming's left-hand rule:

In accordance with Fleming's Left Hand Rule, the thumb, forefinger, and middle finger of the left hand should be positioned perpendicular to one another. The thumb should point in the path of the power exerted by the conductors, the forefinger should point in the magnetic field direction, and the middle finger should point in the path of the electric current.

A vinyl record is played by rotating the record so that an approximately circular groove in the vinyl slides under a stylus. Bum
Fed [463]

Answer:

983.400345675 hits per second

Explanation:

Radius = 14.2 cm

Record turn rate = 33 rev/min

Bump separation = 0.499 mm

Circumference of the record = 2\pi 0.142=0.89221231362\ m

Number of bumps in the groove = \dfrac{0.89221231362}{0.499\times 10^{-3}}=1788.0006285\ bumps

The rate which the bumps hit the stylus = 33\times\dfrac{1788.0006285}{60}=983.400345675

The rate at which the bumps hit the stylus 983.400345675 hits per second
