Field of a Magnetic Dipole So far we have not talked about sources of magnetic fields, but even in our discussion of magnetic forces, we have not made any mention of magnetic charges that behave i...

Torque on a Loop of Wire Let’s use our result for the force on a segment of wire to analyze the case of the effect of a magnetic field on a closed loop of wire. We will choose a simple geometry fo...

Forces on Moving Charged Particles If we run currents through two parallel wires, something unexpected happens – the wires exert forces on each other! One might be inclined at first to explain thi...

Magnetic Materials As with any phenomenon that requires an understanding of what is going on at a microscopic level, magnetism inside of materials like bar magnets is very complicated. We’ll look ...

What’s Up It’s come to my attention that it’s a consensus among the majority that the blog project might not be in the best interests of everyone in its alignment with the national exam. I was deb...

Assignment: Weekly Physics Blog Objective Develop critical thinking and communication skills by engaging with recent developments in physics or analyzing foundational scientific research. Assig...

Pressure in Static Fluids A fluid is a collection of matter that is not a solid. That is, the particles that comprise the matter are not strongly bound to each other in a fixed lattice. This inclu...

Dynamics of Rotational Motion Rotational motion describes how an object rotates around an axis. It is essential for understanding various physical phenomena, from the motion of celestial bodies to...

Rotational Dynamics Torque In this section, we will see interaction of bodies with other objects while rotating and effects of those interactions. Let’s start with the simplest case: turning. Whil...
