Field lines for two negative charges are the same as those for two positive charges except that the direction of the field lines would be reversed.

The direction and magitude of the field at any point in space can be calculated as the vector sum of all the field components there.

Electric field in between a capacitor is uniform until it reaches the ends of the capacitor. Electric field for a cylinder runs radially perpendicular to the cylinder, and is zero inside the cylinder. Potential difference is used in scenarios such as the difference in potential between the two plates of a capacitor, or the positive and negative terminals of a battery. A dipole in an electric field will want to align itself with the electric field, such that the positive end of the dipole is in the direction of the electric field. To calculate the exact potential at a given point, just calculate the individual potential due to the positive charge and the negative charge, then add them together.

The classical example of electrostatic induction is picking up pieces of paper using a comb rubbed against fur.

It's called electrostatic induction because it's static - the charged species polarizes non-charged species by simply being there. E is electric field, A is area that the field goes through, and θ is the angle between the field and the normal of the area. For an enclosed surface, the electric flux is equal to q, the charge inside the enclosure, over the permitivity of free space.

The net electric flux through any enclosed surface is totally dependent on the charge inside.

Magnetic field B exists in a region of space if a moving charge experiences a force due to its motion in that region.

The force is always perpendicular to both the magnetic field and to the velocity of the charge. You are setting the electromagnetic force equal to the centripetal force, which maintains the orbit.

Consider the current in the wire as moving positive charges (by tradition, the direction of the current is defined as the direction of moving positive charges). You can calculate the direction of the force on the wire in the same way using the right hand rule.

UltravioletCan break bonds and excite electrons so much as to eject them, which is why UV is considered ionizing radiation.

Old AAMC Topics: the topics below have either been removed or modified from the official AAMC outline. Individual atoms of Ferromagnetic and Paramagnetic create magnetic fields because they have unpaired electrons.

Diamagnetic atoms don't create magnetic fields because the electrons are paired, so their individual fields cancel out. The magnetic field produced by a solenoid is directly proportional to the number of coils, and to the current.

E is energy per photon, h is Planck's constant, and ν is the frequency of the electromagnetic wave. ELECTROSTATIC FIELDS 1, fields revision from A-level Physics Tutor, your free guide for effective physics revision. The convention for charge relates to early electrostatic experiments with particular materials. The decision to make the charge from glass and silk positive, and the charge from ebonite and fur negative was completely arbitrary.

The force F between two point charges Q1 & Q2 is directly proportional to the product of the charges and inversely proportional to the square of the distance r between them. The symbol εo (epsilon nought) is used to describe the permittivity of free space, ie a vacuum. By definition, a coulomb is the charge passed when a current of 1 ampere flows for 1 second. The electric field strength at a point is equal to the force on a unit charge at the point.

Consider an external force moving Q2 at T an infinitesimal distance δx towards Q1 at S.

Because the distance δx is so small, the repulsive force F may be considered to be constant during the movement. The potential difference between two points in an electric field is numerically equal to the work done in moving a unit + charge from the lower potential point to the higher. From the definition of potential comes the definition of the volt, with specific units for work and charge. The potential difference between two points is 1 volt if one joule of energy is used in moving 1 Coulomb of charge between the points. Simply put, the number of volts is equal to the energy involved in moving 1 Coulomb of charge between points. The diagram below illustrates that the work done in taking charge around a closed loop is zero. Consider a charge +Q being moved by a force F from an arbitrary point A to another point B against an electric field of strength E. The distance moved, δx , is very small, such that the force F may be considered constant.

The force is equal to the force exerted by the field on the charge, but in the opposite direction(note negative sign).

Electric charges of the same sign repel each other and charges of opposite signs attract each other. In the example below, there are more than two charges: $q_1$ positive and $q_2$ and q3 negative.

You can't create or destroy charge, you can only transfer charge from one source to another. The thumb is the direction of a positive charge, the middle finger is the direction of the magnetic field, and the palm faces the direction of the force.

Just treat the direction of the current the same as the direction of velocity of a positive charge.

This is basically the same deal as moving charges, since the unpaired electrons orbiting the nuclei is the same thing as moving charges. Ferromagnetic materials have domains of aligned atoms that make them even more susceptible to be magnetized. The two charges could easily have been transposed, resulting in a positive charge on the electron!

This is because the charges on the conducting cage will rearrange to cancel out any external field.
