pshichka [43]2 years ago
6 0

Answer:

A)an object whose electrons can be aligned in the same direction

Explanation:

Those materials produce magnetic field is known as magnet materials.A magnet is a object whose electrons are aligned in the same direction.

All ferromagnetic materials are magnetic materials. The examples magnetic materials are Co (Cobalt),Ni (Nickel) etc.We know that magnetic filed are produce by the current.

When will an object sink in water, according to Archimedes' principle?​
inna [77]

Answer:

If the buoyant force is greater than the object's weight, the object will rise to the surface and float. If the buoyant force is less than the object's weight, the object will sink. If the buoyant force equals the object's weight, the object will remain suspended at that depth.

Which of the following would decrease the magnetic field around a wire?
shusha [124]
The correct answer is
<span>A. decreasing the current

In fact, the magnetic field produced by a current carrying wire is given by
</span>B(r) =  \frac{\mu_0 I}{2 \pi r}
<span>where
</span>\mu_0 is the vacuum permeability
<span>I is the current in the wire
r is the distance from the wire at which the field is calculated

We see from the formula that the intensity of the field, B, is directly proportional to the current I, so if the current decreases, the magnetic field strength B decreases as well.</span>
