What is the pattern of magnetic field due to a circular coil carrying current?
Magnetic Field Pattern due to a Circular Loop Carrying Current. The magnetic field lines are concentric circles at every point of a current carrying circular loop. The direction of magnetic field at the centre of circular coil is perpendicular to the place of the coil. i.e. along the axis of the coil.
What is shape of magnetic field associated with straight conductor?
The magnetic field associated with a current-carrying straight conductor is in anticlockwise direction.
Does the pattern of the magnetic field depends on the shape of the conductor?
Direction of current determines the pattern of magnetic field generated by a current through a conductor. Yes, the pattern depends on the shape of the conductor. For example- Circular Loop and Straight current-carrying conductor.
Which gives the direction of magnetic field?
The Maxwell right-hand thumb rule indicates the direction of the magnetic field in the direction of the current. If the thumb of the right-hand points along the direction of the current, then the remaining curled fingers of the same hand give the magnetic field direction due to the current.
Which rule is used to determine the direction of force?
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.
What happens if a current carrying conductor is placed in the magnetic field?
When a current carrying conductor is placed on a magnetic field, a mechanical force is exerted on the conductor which can make the conductor move.
What does the arrow of the magnetic field line indicate?
The arrows represent invisible lines of force, known as magnetic field lines. They indicate the direction a compass arrow lies – pointing north–south. Compass directions need to be corrected for the difference between true north and magnetic north. This difference is called magnetic declination.
Will a circular loop of bigger radius?
Answer. Answer: Strength of magnetic field is inversely proportional to radius of circular wire. The deflection of needle of magnetic compass placed at the centre of circular wire of smaller radius is more than that placed at centre of circular wire of larger radius.
