Answer 1

Answer:

1. "The properties of the magnetic field created by solenoid are not the same as the magnetic field of a bar magnet", this statemnet is not true regarding solenoid.

Explanation:

1.  The properties of the magnetic field created by solenoid are not the same as the magnetic field of a bar magnet:

• Magnetic field lines produced by a solenoid are similar to those produced by a bar magnet.
• Outside the magnet, the field lines arise from the north pole and converge in the south pole, whereas inside the magnet, the direction is from south to north.

2. Solenoid having north and south poles:

• Like a bar magnet, current flowing through the coil produces a magnetic field with north and south poles.
• The magnetic field inside the solenoid has a pattern of parallel straight lines. The magnetic field flows from the north pole to the south pole in a solenoid.

3. Magnetic field in solenoid is uniform:

• Inside the solenoid's looping area, the magnetic field is uniform.

• The field is uniform inside the solenoid and a bar magnet.

• The field lines do not cross one another. When electricity is fed through it, it creates a nearly uniform magnetic field in the interior and along the solenoid's axis.

4. A series of copper coils with an electric insulation coating around the object forms a solenoid:

• This is the method to make a solenoid.

Answer 2

Answer:

1. The properties of the magnetic field created by solenoid are not the same as the magnetic field of a bar magnet.

Explanation:

The statement is false because of the following reasons-

1. When current is allowed to pass through the solenoid it produces a magnetic field similar to that of a bar magnet.
2. When the north pole is brought near the end which is connected to the negative terminal of the battery, Bar magnet and solenoid repels each other. The negative terminal acts as the north pole of the solenoid.
3. Which indicates that the end connected to the positive terminal of the battery acts a the south pole.
