Question

Consider a circular loop of wire lying in the plane of the table. Let the current pass through the loop clockwise. Apply the right- hand rule to find out the direction of the magnetic field inside and outside the loop.

Answer 1

Hint: Magnetic field is created around an electromagnet where one end of the electromagnet behaves as a magnetic north pole, while the other behaves as the south pole. By Applying Maxwell's right- hand thumb rule we can find out the direction of the magnetic field inside and outside the loop.

Complete step by step solution:

Electric field and magnetic field which are uniform and are perpendicular to each other which is called crossed electric and magnetic field. Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force. When there is a current in a wire, a circular magnetic field is produced around the wire. A solenoid is a long coil of wire that has been bound many times into a tightly packed coil; it has a shape of a long cylinder. The field lines inside the solenoid are in the form of parallel straight lines .This indicates that the magnetic field is uniform inside the solenoid. Magnetic resonance imaging machines use magnets Electromagnet uses electricity to create their power of magnetism .They can be turned on and off when the electricity is turned on and off. cranes use huge electromagnets to pick up scrap metals in junkyards . Magnets have been used to study bee communication patterns. Strong rare magnet can turn some metal into a magnet. A battery is connected to the circular wire loop to confirm the flow of current. On the plane of the table a circular coil is placed horizontally. By Applying Maxwell's right- hand thumb rule which states that it indicates the direction of magnetic field in the direction of current. In the direction of the current, if we point the thumb of our right hand, then the direction in which our finger wraps gives the direction of the current. On the right side of the wire current is in downward direction. And on the left side the current is in an upward direction.

Note: The most powerful magnet in the universe is actually a star called a Magnestar. Some farmers give their cow a magnet to swallow to prevent accidental eating of nails. Breakfast cereals often contain iron, Some cereals contain enough iron that its pieces are attracted to a magnet.
