Mell What is the direction of the magnetic field if current is upward?
So according to your question ,when current is flowing from West to East thumb points towards right and he curl fingers gives u the direction of feild produced by it ,therefore the magnetic field is cylindrical in direction around it going upwards towards the north side and downward towards the south side of other end …
What is the direction of magnetic field if current is induced vertically up?
Answer: Since the change in flux is increasing in the upwards direction, Lenz’s law tells us that the induced current’s induced magnetic field must resist that, and point downwards on the inside of the loop. Using the right hand rule, we can see that we end up with an induced current in the clockwise direction.
What is the direction of the magnetic field if current is induced vertically up on moving the conductor towards East?
A current flows in a conductor from east to west. The direction of the magnetic field at a point above the conductor is towards north using Maxwell’s right hand thumb rule.
In which direction is the current flowing in which direction is the magnetic field?
What is the direction of the magnetic field at a point ? Explanation: The current flows through this circuit counterclockwise. 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.
What is the relation between magnetic field and current?
A current-carrying wire feels a force in the presence of an external magnetic field. It is found to be F=Bilsinθ F = Bi l sin θ , where ℓ is the length of the wire, i is the current, and θ is the angle between the current direction and the magnetic field.
Which rule is used to determine the direction of force?
Fleming’s left hand rule
The Fleming’s left hand rule can be used to determine the direction of the force, magnetic field and current. A left hand can be held, so that the thumb, first finger and second finger are held mutually perpendicular to each other. The thumb represents the direction of Motion resulting from the force on the conductor.
In which direction is the magnetic field in the center of the solenoid?
The magnetic field lines follow the longitudinal path of the solenoid inside, so they must go in the opposite direction outside of the solenoid so that the lines can form a loop.
Is electric field in the same direction as current?
In general the electric field and the current are not in the same direction. Careful here. Th direction of Positive charge is defined by the direction of the field.
What is the direction of the magnetic field when current flows upward?
In a current carrying wire the lines of force of the magnetic field are circular and concentric with the wire. The direction of the magnetic field is in the direction the fingers of your right hand would curl, if you wrapped them around the wire with your thumb in the direction of the current.
How is the magnetic field of a vertical wire directed?
A vertical wire carries a current upward. The magnetic field north of the wire will be directed: A vertical wire carries a current upward. The magnetic field of the wire will be directed towards west. Using right thumb rule one can get the direction of field lines.
Which is the direction of an induced current?
Upward flux through loop decreases, so need to create upward field Flux into loop is increasing, so need to create field out of loop PHY2049: Chapter 30 25 ConcepTest: Induced Currents ÎWire #1 (length L) forms a one-turn loop, and a bar magnet is dropped through. Wire #2 (length 2L) forms a two-turn loop, and the same magnet is dropped through.
How does a vertical wire carry a current?
A vertical wire carries a current upward. The magnetic field north of the wire will be directed: > A vertical wire carries a c… A vertical wire carries a current upward. The magnetic field north of the wire will be directed: A vertical wire carries a current upward. The magnetic field of the wire will be directed towards west.
