What is the right hand rule for current?
An electric current passes through a solenoid, resulting in a magnetic field. When you wrap your right hand around the solenoid with your fingers in the direction of the conventional current, your thumb points in the direction of the magnetic north pole. An electric current passes through a straight wire.
How do you find force with current and magnetic field?
The force on a current-carrying wire in a magnetic field is F = IlB sin θ.
How do you determine the direction of the magnetic field in the right hand rule?
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 …
When using the right hand rule to determine the direction of the magnetic force on a charge which part of the hand points in the direction that the charge is moving?
We can remember this diagram using the right-hand rule. If you point your pointer finger in the direction the positive charge is moving, and then your middle finger in the direction of the magnetic field, your thumb points in the direction of the magnetic force pushing on the moving charge.
What is Ampere’s right hand rule?
(b) Right hand rule 2 states that, if the right hand thumb points in the direction of the current, the fingers curl in the direction of the field. This rule is consistent with the field mapped for the long straight wire and is valid for any current segment.
How do you find the force of a magnetic field?
We are given the charge, its velocity, and the magnetic field strength and direction. We can thus use the equation F = qvB sin θ to find the force.
Is the right hand rule for conventional current?
Correct answer: Using the right hand rule for the conventional current in the wire, the right thumb is pointed along the wire pointing to the right in the wire at the bottom of the circuit. At point the fingers curl around and point down, into the screen.
What is the direction of the magnetic force on the current in each of the six cases in the figure below?
So you might say north or up is the direction of the force here. And in part d, because the current and the magnetic field lines are parallel there is no force in this picture. There’s only a force if there’s a component of the current that is perpendicular to the magnetic field lines and in this case there is none.
