Electromagnetism
What will be observed if a negatively charged particle is placed at a point where there is an electric field directed north?
The particle will experience no net force since it has negative charge.
The particle will experience a force directed south.
The particle will experience a torque instead of translational motion because of its charge nature.
The particle will remain stationary due to gravitational forces balancing out electrical forces.
In context, what relationship does Faraday's induction state regarding the movement of a magnet induces electromotive force (emf)?
The orientation of the circuit changes produced emf.
The coil size determined the generated emf.
The strength of the source is affected by the applied magnetic field.
The magnitude of the emf produced directly relates to the number of loops cut per second.
Which consequence of Maxwell’s equations accounts for the ability to send and receive radio waves through empty space?
Electromagnetic waves can propagate through vacuum.
Magnetic fields do not have divergence.
Steady currents create static magnetic fields.
Static charges produce constant electric fields.
Which consequence results directly from Ampère-Maxwell's law () in an area with no current flow ()?
Currents reverse direction if there is any variation in nearby electric fields over time.
Magnetic fields cannot exist independently without associated currents nearby.
Electric charge accumulates proportionally to the applied voltage across conductors.
A changing electric field generates a magnetic field even without current flow.
Considering Faraday's law of induction, which scenario would induce the largest voltage in a coil assuming equal strength external changing flux?
Smallest diameter coil maximizing charge densities per area.
Flattest spiral shape ensuring maximum exposure to external flux.
Largest radius coil minimizing charge separation distance.
Coil with the highest number of turns.
According to Faraday's Law of Induction, what happens when the magnetic flux through a loop changes over time?
The permeability of free space within the loop decreases.
An electromotive force is induced in the loop.
Magnetic monopoles are created at the edges of the loop.
A constant current is produced regardless of the circuit resistance.
When considering Gauss's Law for magnetism, magnetic monopoles have never been observed experimentally, this suggests which property for the net magnetic flux passing through any closed surface?
The net magnetic flux through any closed surface remains zero.
The northern pole strength is greater than the strength of the southern pole.
The strength of the magnetic field is directly proportional to the area enclosed by the surface.
The sum of the absolute values of the northern and southern pole strengths is equal.

According to Coulomb's Law, what happens to the force between two charges if the distance between them doubles?
It increases by a factor of four.
It remains unchanged.
It decreases by half.
It decreases by a factor of four.
Considering Ampère-Maxwell's law (), what does it suggest about , if remains zero and there’s a non-uniformly changing electric field over time?
Magnetic fields are caused solely by direct currents and do not arise from varying electric fields like here described.
Magnetic fields cannot exist without actual charges moving due to absence of term (conduction current).
Since equals zero, must also necessarily be zero and not subject to spatial variations or curls.
There would still be a non-zero curl of due to displacement current from changing -field over time.
What property of electric fields allows us to treat the field due to a uniformly charged infinite plane sheet as constant at all points directly above the surface?
The rotational symmetry about any axis in the plane.
The uniform distribution of magnetic dipoles on the plane.
The translational symmetry of the charge distribution.
The spherical symmetry of individual charges on the plane.
