Magnetism: Types, Interactions, and Fields

Posted by admin on Nov 8, 2024 in Physics | 0 comments

Magnetism

A magnet is any substance that attracts iron. Compass needles are typically elongated and geometrically regular.

Types of Magnets

1. Natural Magnets: Magnetite, a natural magnet, attracts magnetic substances. It’s composed of iron oxide. Magnetic substances are those attracted to magnetite.
2. Artificial Permanent Magnets: These substances become magnetized when rubbed with magnetite, retaining their attraction for a long time.
3. Artificial Temporary Magnets: These produce a magnetic field only when

1. Uniform Motion

A. Uniform Straight Motion (USM)

Description:

Motion along a straight path with constant speed and velocity. No change in direction. Acceleration is zero (a = 0 m/s²).

Formula:

v = Δs / Δt
s = s₀ + vt

Graphs:

• Position-time (s-t): Position on the y-axis and time on the x-axis.
• Speed-time (v-t): Speed on the y-axis and time on the x-axis.

B. Uniform Circular Motion (UCM)

Description:

Motion along a circular path. Constant change in direction. Acceleration is normal or centripetal. Angular

Chapter 8: Electromagnetic Induction

Induced Current

The current induced in a coil conductor opposes the change that created it. If the magnetic flux has a negative derivative, the induced field will try to maintain the existing field by creating a field in the same direction. If the derivative is positive, the negative sign indicates that the induced field will oppose the change, preventing the field from growing.

Electromotive Force (EMF)

The first two terms of the EMF depend on the temporal variation

ITEM 1: The Physical Throughout History

Aristotle’s Geocentric Model

Aristotle, one of the most influential figures in the history of physics, proposed a geocentric model of the universe. He believed that the Earth was stationary and located at the center of the universe, with the other planets, including the Sun, revolving around it in perfect circular orbits. This view was consistent with the Greek belief that the circle represented perfect motion and that the universe was finite.

Aristotle divided
