Modern low-power solutions to computer memory rely heavily on the manipulation of the magnetic properties of materials.

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

Now, the movement of an electrical charge induces a magnetic field – and when considered together, the two aspects combine to make an electromagnetic field.

What is causing the Earth’s magnetic field to change so quickly? The reasons behind why Earth’s magnetic field is moving rapidly remain a mystery until today. However, the raging iron core of the ...

Worked Example A proton enters a magnetic field (B = 4 × 10 − 3 T) at the speed of 2.5 × 10 6 m / s. Determine the magnitude and direction of the force on the proton as it enters the field. To work ...

Earth’s magnetic north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.

Problem of radiation of electromagnetic field by a moving around circle at a constant velocity static charge is solved rigorously. In a rotating reference frame both electric and magnetic fields are ...

The magnetic South Pole is also moving toward eastwards across Antarctica. Earth's magnetic poles typically reverse every 300,000 years, but the last pole swap occurred 780,000 years ago, which ...

The Earth's magnetic North Pole is rapidly moving towards Russia, accelerating from 15 km/h to 50-60 km/h in recent decades. This shift impacts navigation systems, GPS, and radiation protection as ...
