I was soldering a magnet wire with a normal copper wire, and while doing that, i burned a small part of the magnet wire, so will this affect the conductance of the wire??

One suggestion I can give is to use the thinnest wire possible, and to cut your wires to the exact length you need to route them around your perfboard.
Another clever technique, which I have not personally tried, is to make a "Wiring Pen" as in this instructables
Wire to SIL socket:
- Put the socket on a bench vice to hold it still.
- Heat up the pin with your soldering iron, then apply a bit of solder. Don't heat too much or you'll melt the plastic spacer between the sockets. Repeat for all pins.
- Strip wire ends. If using multithreaded wire, it might be a good idea to pre-solder the wire ends too.
- Now, holding the iron in one hand and the wire in the other, heat up the pin and touch the wire end on the iron. Once the solder melts, move the wire end into the molten solder, then move the soldering iron away. Hold the wire still until the solder solidifies. A stable posture will help.
- Inspect. If it looks like a cold joint (matte grey, brittle), add a bit of fresh solder and redo the joint applying afterheat a bit longer.
- Put a 2-3 cm. piece of <3mm heat shrink tube over the joint, pin and wire. Shrink it tight to make it more durable.
Wire to pad:
- Basically the same thing - apply enough pre-solder on the pad to immerse the wire end.
General advice:
- The thicker the wire / the larger the foil you're soldering, the longer pre-heating is required on that surface.
- If the metal you're trying to solder is in contact with eg. metal pliers or bench vice, the tool will conduct lots of heat away making your work difficult.

Most likely you burned the insulation, not the copper part of the wire. Be aware that burned insulation no longer insulates, but also creates a layer that makes soldering difficult.
It's not clear what part of the wire you burned, and whether this was accidental or not. If you deliberately burned the end to remove the insulation, then finish the job by lightly scraping it off. Once you get bare copper color, it will solder fine. If you burned some other part of the wire accidentally, like part of a coil that is already wound, you may have problems. Look carefully to see if adjacent windings are now touching. You might be able to fix this by brushing off or very carefully scraping off the burnt insulation, then fixing the wire in place with epoxy after making sure nothing is touching.
