an electromagnet's strength depends on the amount of current that flows through it. Permanent magnets can lose their magnetic properties such as their ability to give off a magnetic field when they're heated to a certain temperature.
To increase the strength of an electromagnet, you can increase the strength current, and there are several ways to do that. You can also increase the number of windings, lower the ambient temperature or replace your non-magnetic core with a ferro-magnetic material.It...

Using the relation δΔ = 2δσ = μBg||δB, one obtains δB = 17 μT, i.e., the strength of an external magnetic field can be determined with the precision δB ≈ 17 μT. It is worth noting that the range of measured magnetic fields can be very broad ...
This field can be increased manyfold by inserting a piece of soft iron or other ferromagnetic material into the core; the resulting arrangement constitutes an electromagnet. Following Oersted's discovery the various magnetic effects of an electric current were extensively investigated by J. B. Biot,...
The strength of the interlayer exchange coupling in [Fe/MgO] $$_N$$ (001) superlattices with 2 ≤ N ≤ 10 depends on the number of bilayer repeats (N). The exchange coupling is antiferromagnetic for all the investigated thicknesses while being nine times

Two additional tests have been performed to check the induced voltages in cases 5 and 6: (i) increasing the field strength by adding additional magnets to the setup, as it was considered that perhaps the field was too weak at the position of the closing wire due to it being further away...
Then, the decreasing grain size in CP-Ti leads to significant increases in its hardness and/or strength [33]. In this case, Fig. 4 shows that Ti-15Zr had small needles in the microstructure, which could cause changes in the mechanical properties compared to those of Ti-5Zr and Ti-10...
