Fundamental Physics/Electromagnetic force
Electricity charge[edit | edit source]
Electric charge is refered to matter that carries electricity . In natural state, all matter is neutral in charge . When matter gives or receives electron (negatively charged particle) , matter becomes electric charge . Static Electricity the process matter acquires charged particle (electron) to become electric charge . Matter receives electron will become negative electric charge . Matter gives electron will become positive electric charge
- Matter + e- -- > Negative Charge (-)
- Matter - e- -- > Positive Charge (+)
Electric charge properties[edit | edit source]
Charge Quantity[edit | edit source]
Electric charge has a symbol Q measured in Coulomb unit C . One coulomb charge contains N-m
Positive electric charge has symbol +Q carries +1C . Negative electric charge has symbol +Q carries +1C
Electric Field[edit | edit source]
All charge process electric field lines point inward or outward surround charge . For negative charge, the electric field lines point inward . For positive charge, the electric field lines point outward.
Magnetic Field[edit | edit source]
All charge process circular magnetic field lines point inward or outward surround charge . For negative charge, the electric field lines point inward . For positive charge, the electric field lines point outward.
- Negative Charge . B ↑
- Positive Charge . B ↓
Electric charge interaction[edit | edit source]
Electric charges interaction[edit | edit source]
Coulomb discovered that charges of the same polaities will repulse . Charges of different polarities will attract . Negative charge will attract positive charge . The force of attraction is called Electrostatic force or Coulomb force . Electrostatic force has a symbol FQ measured in unit Newton N
Electrostatic force or Coulomb force is used in calculating the force of negative charge attracts positive charge
Electric charge and electricity interaction[edit | edit source]
Ampere discovered that, electricity exerts a force to force electric charge to move in a linear path will create a field of electric lines called Electric field . This force is called Electrodynamic force or Ampere force which has a symbol FE measured in unit Newton N
Electric charge and magnet interaction[edit | edit source]
Lorentz discovered that when electric charge travels through a magnet, magnet exerts a force to deflect
Electric charge interactions force[edit | edit source]
- Electrostatic force or Coulomb force is used in calculating the force of negative charge to attract positive charge
- Electrodynamic force or Ampere force is used in calculating the force of electricity to make electric charge to move in a straight line path
- Electromagnetomotive force or Lorentz force is used in calculating the force of magnet to make electric charge to move in a straight line perpendicular to the original path
- Electromagnetic force is the sum of the 2 electrodynamic and electromagnetomotive force
