A freely pivoting bar magnet
(such as a compass needle) is placed in a magnetic field created by
other sources. The figure correctly shows the alignment of the
compass in the external magnetic field.
Is this statement about the figure
True or False??

1-A compass is held horizontally. The silver end of the needle
points towards geographic south and the blue end points towards
geographic north. The compass is then brought near one pole of a
horseshoe magnet. The blue end of the compass points towards this
pole. What is the polarity of this pole on the magnet?

The earth's magnetic field
appears as if it were produced by a strong permanent magnet
embedded in its core. In the figures below, the earth is shown with
the northern hemisphere on top, its core magnet is illustrated by
the overlayed bar magnet, and a compass is illustrated as a diamond
with a black tip at its magnetic north end. Which figure has the
core magnet and compass magnet in roughly the proper
orientation?

III. Mapping the Field Around a Bar Magnet: An Observation Experiment Purposes: Design an experiment to take appropriate data to find a relationship. Construct a mathematical model to describe that relationship Description: Your task is to use a compass to map the magnetic field of a small magnet. Construct a circle of radius 10 cm on a clean sheet of paper, and mark points on the circle every 30°. Place the bar magnet so that its center is resting at...

A bar magnet is aligned east-west, with its center 39 cm from the center of a compass (see figure below). The compass is observed to deflect 67 away from nortn as shown, and the horizontal componont of tho Earth's magnotic tiod is known to bo 2 × 15-5 T. Northt θ (a) Label the N and S poles of the bar magnet and explain your choice The N pole is on the left and the S pole is on the...
A bar magnet with magnetic dipole moment 0.6A · m2 lies on the negative x axis
A bar magnet with magnetic dipole moment 0.6A · m2 lies on the negative x axis, as shown in the figure below. A compass is located at the origin. Magnetic north is in the negative z direction. Between the bar magnet and the compass is a coil of wire of radius 3.5 cm, connected to batteries not shown. The distance from the center of the coil to the center of the compass is 8.9 cm. The distance from the center...

1. The stack of magnets works as one big bar magnet. Do the poles change when you divide the magnet into pieces? 2. In step 3 of the experiment, do both sides of the magnet attract the metal surface? Explain how a single magnet can repel the rest of the stack, but still stick to the other surface. 3. How does the magnet attract something that is originally non?magnetic? 1. Describe the direction of the compass needle as you moved...
