Eugen Goldstein was a German physicist who is best known for his experiments involving the behavior of positively charged particles in a gas. In 1886, he discovered the positive ray, a type of particle that is now known as the proton. He was the first to suggest that a beam of positive particles could be …

Julius Plucker is known for his experiments and discoveries related to electric charge. He is credited with the discovery of what is now known as the Plucker’s Law of Electric Charge. This law states that the amount of electric charge stored on an object is proportional to the product of the distance between two points …

Heinrich Geissler was a German physicist who is best known for his work on the design and construction of a variety of discharge tubes. He was the first to use a partially-evacuated tube to produce electrical discharge in a controlled manner, which allowed for the observation of phenomena such as electrical glow and the first …
Michael Faraday is known for his groundbreaking work in the field of electricity and magnetism. He is credited with discovering and naming the laws of electrochemistry, including the laws of electrolysis. He also developed the first electric motor and generator, which allowed for the first electric power plants. Faraday’s experiments in the field of electricity …

Sir Humphry Davy conducted a series of experiments to investigate the nature of electric charge. He developed theories about positive and negative charges, and discovered that electric current could be used to decompose substances. In his experiments, Davy used voltaic piles, which were the first batteries, to create a steady electric current. He also used …

All matter is made up of extremely small particles called atoms. Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties. Atoms cannot be subdivided, created, or destroyed. Atoms of different elements combine in simple whole-number ratios to form chemical compounds. …
Dalton’s atomic theory states that all matter is composed of tiny indivisible particles called atoms, which are indestructible and indivisible. Atoms of the same element are identical in their chemical and physical properties, but atoms of different elements have different properties. Atoms of different elements can combine with each other in different proportions to form …

A molecule is a group of atoms held together by chemical bonds. Molecules can exist as a distinct particle, or as a part of a larger chemical structure. Examples of molecules include water (H2O), carbon dioxide (CO2), and proteins.
Increase the Number of Turns: Increasing the number of turns of wire in the coil increases the magnetizing force, thus increasing the strength of the electromagnet. Increase the Current: Increasing the current through the coil increases the strength of the electromagnet. Increase the Core Material: Increasing the core material increases the magnetic field, thus increasing …
