Question

1 - The Earth's geological north pole is its magnetic south pole.

True

False

2- Mangetic field is generated by electric currents.

True

False

3 - A bar magnet can have a single north pole without a south pole.

True

False

4 - Magnetic field lines form closed loops.

True

False

5 - Magnetic field is a vector.

True

False

6 - We will NOT be using an Excel sheet in this lab to map out the field of bar magnets.

True

False

7- A field pointing into the magnetic probe along the axis produces a positive reading in DataStudio; while a field point out of the probe along the axis produces a negative reading.

True

False

Explanation / Answer

1) since like poles attract each other,so the statement is True

2) according to ampere's law B= mu_0*i/(2*pi*r)

So Mangetic field is generated by electric currents.

True

3) monopoles does not exists

So A bar magnet can have a single north pole without a south pole.

False

4) outside of the magnet the field lines startfrom north pole and ends on south pole and it will continuous inside the bar magnet also

So Magnetic field lines form closed loops.

True

5) magnetic field is having both magnitude and directionand obeyts vector laws of addition so

Magnetic field is a vector.

True

6) no need of using excel sheet to map out simply

so the given statement is True

7) if into is positive the opposite direction out of the probe will be negative since the magnetic field is a vector quantity

So it is True
