Magnetic Infusion -> Telekinetic Blast

Would a Kineticist attacking with a Telekinetic Blast gain the +4 bonus on attack rolls from a target hit by Magnetic Infusion, provided that the Kineticist attacks with a metal weapon? Would loosening the aetheric strands, as detailed in the blast, make a difference?

Element(s) air or earth; Type substance infusion; Level 3; Burn 2

Saving Throw none

Your kinetic blast causes your foes to become mildly magnetic.

Whenever an infused blast deals damage to a foe, attacks made with metal weapons (including metal kinetic blasts) against that foe receive a +4 bonus until the end of your next turn, and the foe takes a –4 penalty on Reflex saving throws to avoid metallic objects.

Element(s) aether; Type simple blast (Sp); Level —; Burn 0
Blast Type: physical; Damage bludgeoning, piercing, or slashing

You throw a nearby unattended object at a single foe as a ranged attack. The object must weigh no more than 5 pounds per kineticist level you possess. If the attack hits, the target and the thrown object each take the blast's damage. Since the object is enfolded in strands of aether, even if you use this power on a magic weapon or other unusual object, the attack doesn't use any of the magic weapon's bonuses or effects; it simply deals your blast damage. Alternatively, you can loosen the strands of aether in order to deal damage to both the object and the target as though you had thrown the object yourself (instead of dealing your normal blast damage).

You substitute your Constitution modifier for your Strength modifier if throwing the object would have added your Strength modifier on the damage roll, and you don't take the –4 penalty on the attack roll for throwing an object that wasn't designed to be thrown. In this case, the object's special effects apply (including effects from its materials), and if the object is a weapon, you must be proficient with it and able to wield it with one hand; otherwise, the item deals damage as a one-handed improvised weapon for a creature of your size.

I'd say you only get the bonus when loosening the strands. The limitations on the regular blast are pretty constrained and sort of metagame-y. Basically, without loosening the strands, the contained object is completly without type or distinction.

No ıt wouldnt.Just add that to one of 10 million things that you wish a kineticist can do but it never will.
