The strength of an electromagnets magnetic field depends on:
factors on which magnetic field a bar magnet depends :- 1. pole strength of the magnet 2. medium in which the bar magnet is present(since the permittivity changes) factors on which external magnetic field(B) of a current carrying coil depends:- 1. the amount of current flowing through the conductor 2. the perpendicular distance of the point from the conductor. 3. medium in which the conductor is present(since the permittivity changes)
Factors affecting the magnetic field strength of a solenoid are: - length of the solenoid - diameter of the solenoid - current through the coil around the solenoid - number of turns of the coil of current around the solenoid, usually turns of wire - material in the core
The four factors that cause ocean currents: (1) Planet rotation, (2) Wind, (3) Density of the water (depends on temperature and salinity), and (4) Gravitation of the moon and earth. Direction and strength depends on the shape of the shoreline, depth and shape of the bottom, and other currents.
temperature, confining pressure, rock type, and time
When rocks are formed, usually from lava flows, the magnetic orientation of them is set as they solidify. As these rocks are affected by continental drift and other factors such as earthquakes, the original magnetic orientation remains. Using the known strengths of the earth's magnetic field over time, it is possible to then tell where these rocks originally emerged.
Identify factors which affect the power of electromagnet?
One of them is how many coils go around the electromagnet. also the amout of current flow< and the type of core material.
The strength of electromagnet depends on the electric current flowing through the core because when the current is stopped, the core is no longer magnetized and the rate of change of flux linkage.
The strength of an electromagnet is determined by the density of coils surrounding the magnet, and the rate of current passing through those coils.

To increase the strength of a magnet you need to stack it between two stronger magnets or electromagnets. To weaken it, you'd have to heat it up, or use the same method as when strengthening, only this time you should flip the magnet so it would repel the stronger (electro)magnets.
The strength of induced current depends on the number of coils of the cunductor and the strength of the magnet.
The strength of an electric field depends on the charge that causes it, and on the distance from the charge.
Number of loops and Battery voltage
Break in the circuit or loss of magnetic strength of the magnet can result in to no generation
Number of loops and Battery voltage
The voltage would depend on the speed of the magnet. It also depends on other factors, e.g. the angle between the magnetic field lines and the movement, and the strength of the magnetic field at that point.
