Flemings Left-hand Rule (ht Only) (GCSE Physics)

A student sets up a small DC motor and observes the coil side nearest them moves toward them. Using Fleming’s left-hand rule, which combination of field and current directions could explain that motion (assume conventional current direction shown)?

In a single-turn rectangular coil in a uniform downward magnetic field, the front face of the coil carries current left-to-right while the back face carries current right-to-left. Using Fleming’s left-hand rule, the front face experiences a force in which direction relative to the coil?

A moving-coil loudspeaker has a magnetic field from the permanent magnet directed left-to-right. If a positive current pulse flows from the front of the cone into the coil (front ? back), which initial direction does the coil (and cone) move?

Fleming’s left-hand rule is applied using the direction of conventional current. Which statement about electron flow is correct?

In a loudspeaker, the voice coil sits in a radial magnetic field. An alternating current produces an alternating force (motor effect) on the coil. Which of these correctly links the direction reversals?

An electron beam (negative charges) moves to the right through a magnetic field pointing into the page. Using Fleming’s left-hand rule for conventional current, which way is the magnetic force on the electrons?

In a typical DC motor the commutator reverses the current in the rotating coil every half-turn. Why is this necessary when combined with Fleming’s left-hand rule?

A straight conductor lies across a uniform magnetic field directed from left to right. Conventional current flows upward along the conductor. Using Fleming’s left-hand rule, what is the direction of the magnetic force on the conductor?

An engineering drawing shows a coil side at the front with current flowing left and the magnetic field directed from top to bottom. Using Fleming’s left-hand rule, is the front side pushed toward or away from you and why?

A motor designer uses Fleming’s left-hand rule to check directions. If the magnetic field points from the magnet’s north to south (rightwards) and the force on the conductor must be upwards, which way must the conventional current in that conductor flow?

A long straight conductor runs into the page (away from you) through a region where the field is from left to right. Using Fleming’s left-hand rule, what is the direction of the magnetic force on the conductor when conventional current flows into the page?
