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

Homework Answers

Answer #1


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

Which of the following statements is correct? Question 1 options: Magnetic field lines come out of the magnetic south pole of the magnet and enter at the north pole of the magnet. Like poles of magnets attract each other and unlike poles repel. The north pole of a magnet points toward the Earth's geographic north pole. If you cut a bar magnet in half, you get one piece with just a north magnetic pole on it and the second piece...

A magnetic field, strength 3T, has a direction out of the page. A loop of wire sits in the field and on the plane of the page (area vector of loop is out of page). The loop is much smaller than the extent of the field. The magnetic field starts to slowly change at a rate of -0.0001T/s. Looking down on the loop, which statement is correct? A. Magnetic flux out of page decreasing; anti-clockwise current induced in loop B....

In magnetic resonance imaging (MRI), a patient lies in a strong 1- to 2-TT magnetic field B⃗ B→ oriented parallel to the body. This field is produced by a large superconducting solenoid. The MRI measurements depend on the magnetic dipole moment μ⃗ μ→ of a proton, the nucleus of a hydrogen atom. The proton magnetic dipoles can have only two orientations: either with the field or against the field. The energy needed to reverse this orientation ("flip" the protons) from...
