Which rule is used to find the direction of magnetic field on a straight current carrying conductor?

Which rule is used to find the direction of magnetic field on a straight current carrying conductor?

Maxwell’s right-hand thumb rule
(i) Maxwell’s right-hand thumb rule: Magnetic field produced around a straight conductor carrying current. The Maxwell right-hand thumb rule indicates the direction of the magnetic field in the direction of the current.

Which rule is used for direction of magnetic field?

The right hand rule states that: to determine the direction of the magnetic force on a positive moving charge, point your right thumb in the direction of the velocity (v), your index finger in the direction of the magnetic field (B), and your middle finger will point in the direction of the the resulting magnetic force …

Which law gives the direction of magnetic field?

Option A: As discussed above, according to the Biot-Savart law, if the thumb of the right hand is placed in the direction of the current flow, then the finger curls will give the direction of the magnetic field. So, the right-hand thumb rule is used to find the direction of the magnetic field lines.

Which rule is used to find the direction of induced current?

Fleming’s right-hand rule
Fleming’s right-hand rule (for generators) shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field. It can be used to determine the direction of current in a generator’s windings.

Which rule is applied to find the direction of magnetic fields in a solenoid coil?

Right-hand rule can be used to find the direction of the magnetic field. In this case, point the wrapped fingers (along the coil) in the direction of the conventional current. Then, the thumb will point to the direction of magnetic field within the solenoid.

Which rule is used to find the direction?

Whenever a current carrying conductor is placed in a magnetic field, it experiences a force due to the magnetic field. The direction of force acting on the conductor can be found using Fleming’s Left Hand Rule.

What rule should you use to determine the direction of induced emf in a coil?

The direction of the induced e.m.f. can be determined by Fleming’s right hand rule .

Which law gives the direction of induced emf?

Lenz’s law
Lenz’s law gives the direction of induced emf with respect to the change in magnetic flux but Fleming’s law gives the direction of induced emf more accurately.

Which rule is used to find the direction of induced current class 10?

Fleming’s right hand rule
Fleming’s right hand rule.

What is the direction of magnetic field?

The direction of magnetic field lines is defined to be the direction in which the north end of a compass needle points. The magnetic field is traditionally called the B-field.

What is the right hand rule for magnetic field?

Right-Hand Rule #2 (RHR #2) Right-Hand Rule #2 determines the direction of the magnetic field around a current-carrying wire and vice-versa Using your right-hand: Curl your fingers into a half-circle around the wire, they point in the direction of the magnetic field, B Point your thumb in the direction of the conventional current.

How do you determine the direction of a magnetic field?

How do you Determine the Direction of the Magnetic Field. Rule : The direction of the magnetic lines of force is related with the direction of the current by the right hand thumb rule. The rule states : Curl the four fingers of the right hand on the palm, keeping the thumb stretched out at right angles.

How do you find the magnetic force on a current carrying conductor?

The magnetic force on current-carrying conductors is given by where I is the current and l is the length of a wire in a uniform magnetic field B. Describe the error that results from accidently using your left rather than your right hand when determining the direction of a magnetic force.

How do you measure the direction of current in a circuit?

Curl the four fingers of the right hand on the palm, keeping the thumb stretched out at right angles. The thumb is straight and the fingers are circular. In case 1. thumb represents the direction of the current in the straight wire and curling of fingers represents the direction of the circular magnetic lines of force.
