Measurement of Magnetic Force and Energy Conservation

Flashcards covering key concepts from the notes related to magnetic forces, charge interactions, and energy principles.

Magnetic Force (F)

Depends on the sign of the test charge and the cross product of the directions.

Test Charge (q)

The charge whose behavior is being observed, with its direction related to electric fields and magnetic fields.

Conservation of Energy

In the context of charged particles, total energy is conserved during acceleration through a voltage.

Electron Acceleration

When an electron is accelerated from rest through a voltage, its kinetic energy increases.

Helmholtz Coils

Devices used to create uniform magnetic fields; current measured in Amps.

Current (I)

Flow of electric charge, which influences the magnetic field in Helmholtz coils.

Voltage (V)

An electric potential difference that causes acceleration of charges like electrons.

Slope Calculation in Graphs

In experimental data, slope is calculated from measurements of velocity squared divided by two.

Conversion of Units

In scientific measurements, it is often necessary to convert values into standard units for analysis.

Graph for Each Value of Current

Separate graphs are plotted to analyze the relationship of velocity squared with varying current values.
